mwifiex: get rid of global user_rmmod flag
bus.remove() callback function is called when user removes this module
from kernel space or ejects the card from the slot. The driver handles
these 2 cases differently. Few commands (FUNC_SHUTDOWN etc.) are sent to
the firmware only for module unload case.
The variable 'user_rmmod' is used to distinguish between these two
scenarios.
This patch checks hardware status and get rid of global variable
user_rmmod.
