[PATCH] staging: qlge: Add bool type to qlge_idc_wait()

[Gilbert Adikankwu <gilbertadikankwu@gmail.com>]

Reported by checkpatch:

WARNING: else is not generally useful after a break or return

The idea of the break statements in the if/else is so that the loop is
exited immediately the value of status is changed. And returned
immediately. For if/else conditionals, the block to be executed will
always be one of the two. Introduce a bool type variable 's_sig' that
evaluates to true when the value of status is changed within the if/else
block.
