Luca Coelho 0c38cad1d1 iwlwifi: mvm: check return value of rs_rate_from_ucode_rate()
commit 3d71c3f1f5 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.
