[PATCH 6/6] ALSA: rawmidi: propagate resize_runtime_buffer() error in input_params

[Omer Cohen <nevergfx1@gmail.com>]

snd_rawmidi_input_params() calls resize_runtime_buffer() but ignores
its return value, unconditionally returning 0.  This silently swallows
-ENOMEM (allocation failure), -EINVAL (invalid parameters), and -EBUSY
(buffer in use).

When resize fails, the framing and clock_type parameters are still
applied to the substream, but the buffer remains at its old size.
This leaves the stream in an inconsistent state where the configured
framing mode does not match the buffer layout.

Return the error from resize_runtime_buffer().
