firmware: qcom: uefisecapp: Fix deadlock in qcuefi_acquire()
If the __qcuefi pointer is not set, then in the original code, we would
hold onto the lock. That means that if we tried to set it later, then
it would cause a deadlock. Drop the lock on the error path. That's
what all the callers are expecting.
