Subject: [PATCH] iwlwifi: mvm: remove setting of 'sta' parameter

cppcheck reports
[drivers/net/wireless/intel/iwlwifi/mvm/rs.c:2686]: (warning) Assignment of function parameter has no effect outside the function. Did you forget dereferencing it?

The setting of the 'sta' parameter is not needed.  In the if-check that sets it
to NULL, mvm_sta is also set to NULL.  Then the next statement checks if
mvm_sta is NULL and does an early return. So remove setting sta.
