tee: optee: add missing mutext_destroy in optee_ffa_probe

[ Upstream commit b5e22886839ae466fcf03295150094516c0fd8eb ]

The error handling code of optee_ffa_probe misses the mutex_destroy of
ffa.mutex when mutext_init succeeds.

Fix this by adding mutex_destory of ffa.mutex at the error handling part
