[PATCH v2 7/8] staging: r8188eu: remove the bInSuspend loop

[Martin Kaiser <martin@kaiser.cx>]

Remove the loop in rtw_pwr_wakeup that waits while the system is
suspended.

pwrpriv->bInSuspend is set in rtw_suspend and cleared in rtw_resume. These
functions are the .suspend and .resume functions of the struct usb_driver
for r8188eu.

A usb_driver's suspend and resume functions are called when the entire
system goes into suspend or runtime suspend.

All of the code paths for rtw_pwr_wakeup start at ioctl handlers.

We can remove the loop that checks bInSuspend. It's not possible to call
an ioctl while the entire system is suspended.

I tried to track down who calls suspend and resume of an usb_driver. My
understanding is that all of these calls come from the pm layer and that
the suspend and resume affect the whole system, not just the usb device.
