Hou Tao 42815f8ac5 fuse: set FR_PENDING atomically in fuse_resend() 
When fuse_resend() moves the requests from processing lists to pending
list, it uses __set_bit() to set FR_PENDING bit in req->flags.

Using __set_bit() is not safe, because other functions may update
req->flags concurrently (e.g., request_wait_answer() may call
set_bit(FR_INTERRUPTED, &flags)).

Fix it by using set_bit() instead.

Fixes: 760eac73f9 ("fuse: Introduce a new notification type for resend pending requests")
