iwlwifi: mvm: set MAC_FILTER_IN_BEACON correctly for STA/P2P client

iwlwifi: mvm: set MAC_FILTER_IN_BEACON correctly for STA/P2P client

In commit cad3f08c (iwlwifi: mvm: enable MAC_FILTER_IN_BEACON when
forced_assoc_off is set) the code to set the MAC_FILTER_IN_BEACON flag
was accidentally moved to the main block of the if statement, while it
should be in the else block instead.  Move it to the right place.

Fixes: cad3f08c23de ("iwlwifi: mvm: enable MAC_FILTER_IN_BEACON when forced_assoc_off is set")
