[media] lirc_imon: do not leave imon_probe() with mutex held
Commit af8a819a2513 ("[media] lirc_imon: simplify error handling code")
lost mutex_unlock(&context->ctx_lock), so imon_probe() exits with
the context->ctx_lock mutex acquired.
The patch adds mutex_unlock(&context->ctx_lock) back.
Found by Linux Driver Verification project (linuxtesting.org).
Fixes: af8a819a2513 ("[media] lirc_imon: simplify error handling code")
