[PATCH 5/9] iwlwifi: mvm: move umac_error_event_table validity check to where it's set

[Luca Coelho]

From: Luca Coelho <luciano.coe...@intel.com>

There's no point in checking the validity of the
umac_error_event_table pointer every time we generate a dump.  It's
cleaner to do so when we read the value, namely when we receive the
alive data.
