CVE-2024-46868

firmware: qcom: uefisecapp: Fix deadlock in qcuefi_acquire()

In the Linux kernel, the following vulnerability has been resolved:

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.
