[PATCH AUTOSEL 4.19 197/237] wil6210: fix L2 RX status handling

From: Maya Erez <merez@codeaurora.org>

[ Upstream commit 04de15010aa42a92add66b159e3ae44b4287390f ]

L2 RX status errors should not be treated as a bitmap and the actual
error values should be checked.
Print L2 errors as wil_err_ratelimited for easier debugging
when such errors occurs.
