[PATCH 09/14] staging: r8188eu: remove the global DriverState

[Martin Kaiser]

DriverState in struct adapter is never set. It remains 0 (DRIVER_NORMAL)
all the time, DriverState != DRIVER_DISAPPEAR is always true.

Both DriverState and the check can be removed. enum driver_state contains
the possible values of DriverState. This enum can be removed as well.
