George Cherian 2cf93bea3d usb: gadget: f_mass_storage: call try_to_freeze only when its safe 
Call try_to_freeze() in sleep_thread() only when it's safe to sleep.
do_read() and do_write() calls sleep_thread with lock held.
Make sure these won't call try_to_freeze() by passing can_freeze flag
to sleep_thread.

Calling try_to_freeze() with a lock hold was done since day one in
f_mass_storage but since commit 0f9548ca1 ("lockdep: check that no
locks held at freeze time") lockdep complains about it.
