iwlwifi: mvm: check return value of rs_rate_from_ucode_rate()
commit 3d71c3f1f50cf309bd20659422af549bc784bfff upstream.
The rs_rate_from_ucode_rate() function may return -EINVAL if the rate
is invalid, but none of the callsites check for the error, potentially
making us access arrays with index IWL_RATE_INVALID, which is larger
than the arrays, causing an out-of-bounds access. This will trigger
KASAN warnings, such as the one reported in the bugzilla issue
mentioned below.
This fixes https://bugzilla.kernel.org/show_bug.cgi?id=200659
