usb: yurex: make waiting on yurex_write interruptible
[ Upstream commit e0aa9614ab0fd35b404e4b16ebe879f9fc152591 ]
The IO yurex_write() needs to wait for in order to have a device
ready for writing again can take a long time time.
Consequently the sleep is done in an interruptible state.
Therefore others waiting for yurex_write() itself to finish should
use mutex_lock_interruptible.
