[PATCH] tee: optee: add missing mutext_destroy in optee_ffa_probe

[Dongliang Mu]

From: Dongliang Mu <mudongliangabcd@xxxxxxxxx>

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

Fixes: aceeafefff73 ("optee: use driver internal tee_context for some rpc")
