hid_warn_ratelimited() is needed. Add the others as part of the block.

[ Upstream commit 2c85c61d1332e1e16f020d76951baf167dcb6f7a ]

commit 0a3fe972a7cb ("HID: core: Mitigate potential OOB by removing
bogus memset()") enforced the provided data to be at least the size of
the declared buffer in the report descriptor to prevent a buffer
overflow. However, we can try to be smarter by providing both the buffer
size and the data size, meaning that hid_report_raw_event() can make
better decision whether we should plaining reject the buffer (buffer
overflow attempt) or if we can safely memset it to 0 and pass it to the
rest of the stack.

HID: pass the buffer size to hid_report_raw_event

This commit introduces a bufsize parameter to hid_report_raw_event() to help
distinguish between the actual payload size and the buffer capacity. This allows
the HID core to safely memset zero-pad short reports without causing
out-of-bounds writes if the buffer is too small.

[Severity: High]
Does this new check unconditionally reject short reports for callers that pass
the payload size as the buffer size?

Since bsize is checked against rsize and returns -EINVAL, if bsize
happens to equal csize, the subsequent csize < rsize check and its memset
zero-padding logic become unreachable dead code.

[Severity: High]
Does initializing bufsize to size here lose the actual allocation capacity
of the buffer?

By constraining bufsize to the payload size, this ensures that bsize == csize
in hid_report_raw_event(), which means valid short reports missing trailing
zero bytes will be rejected rather than padded.

[Severity: High]
Should this pass sizeof(buf) as the buffer size instead of size?

Since size is the number of bytes read from the kfifo (the payload size),
passing size as both the buffer size and data size prevents the short-report
zero-padding logic from working correctly.
