iwlwifi: mvm: fix inactive TID removal return value usage

commit e6d419f943318e2b903e380dfd52a8dda6db3021 upstream.

The function iwl_mvm_remove_inactive_tids() returns bool, so we
should just check "if (ret)", not "if (ret >= 0)" (which would
do nothing useful here). We obviously therefore cannot use the
return value of the function for the free_queue, we need to use
the queue (i) we're currently dealing with instead.
