Evgeny Novikov 98cb3a055b media: ttusb-dec: avoid release of non-acquired mutex 
[ Upstream commit 36b9d695aa ]

ttusb_dec_send_command() invokes mutex_lock_interruptible() that can
fail but then it releases the non-acquired mutex. The patch fixes that.

Found by Linux Driver Verification project (linuxtesting.org).
