Due to needs a tackling the deficiency of the AP API, it's necessary to
ensure that in non-blocking mode previous AP executed command is
finished before starting new one.
To remedy above:
1) execute AcquireSpinLock instead AcquireSpinLockOrFail - this will
ensure time "window" to eliminate potential race condition between
BSP and AP spinLock release in non-blocking mode.
This also will eliminate possibility to start executing new AP
function before last is finished.
2) remove returns EFI_STATUS - EFI_NOT_READY - in new scenario returned
status is not necessary to caller.
