Peng Fan d71ed2c9f1 mailbox: Not protect module_put with spin_lock_irqsave ...

[ Upstream commit dddbd233e67e792bb0a3f9694a4707e6be29b2c6 ]

&chan->lock is not supposed to protect 'chan->mbox'.
And in __mbox_bind_client, try_module_get is also not protected
by &chan->lock. So move module_put out of the lock protected
region.
