firmware: qcom: uefisecapp: fix efivars registration race
Since the conversion to using the TZ allocator, the efivars service is
registered before the memory pool has been allocated, something which
can lead to a NULL-pointer dereference in case of a racing EFI variable
access.
Make sure that all resources have been set up before registering the
efivars.
