pack: Remove flash wifi_fw command

Browse source 
'flash wifi_fw' command writes into flash based
on 'rootfs' partition offset. After sysupgrade,
flashing single image at u-boot write wifi firmware
into failsafe partitions because post sysupgarde
primary and failsafe partitions are swapped vice-versa.
Single image always boots with primary partitions, and
the wifi firmware flashed into failsafe partition won't
be loaded subsequently q6 will crash.

This patch resolves issue by using "ubi" command's instead
of "flash wifi_fw" command.
