wifi_drv: call schedule() in sleep functions

Browse Source 
The jiffies are only updated on each round of scheduling the runnable
tasks. We have to schedule the current task that executes the sleep
call to update the jiffies count and thereby preventing the task from
entering an endless loop when using a statement like
'while (!time_after(jiffies, now + timeout)) { msleep(1); }'.

Related to #1326.
