gcc warns about what it thinks is an uninitialized variable
access:

drivers/net/wireless/intel/iwlwifi/mvm/fw.c: In function 'iwl_mvm_sar_find_wifi_pkg.isra.14':
drivers/net/wireless/intel/iwlwifi/mvm/fw.c:1102:5: error: 'wifi_pkg' may be used uninitialized in this function [-Werror=maybe-uninitialized]

That problem cannot really happen, as we check data->package.count
to ensure that the loop is entered at least once.
However, something that can indeed happen is returning an incorrect
wifi_pkg pointer in case none of the elements are what we are looking
for.

This modifies the loop again, to only return a correct object, and
to shut up that warning.
