Michael Brown d8c500b794 [efi] Drop to TPL_APPLICATION when gathering entropy

Commit c89a446 ("[efi] Run at TPL_CALLBACK to protect against UEFI
timers") introduced a regression in the EFI entropy gathering code.
When the EFI_RNG_PROTOCOL is not present, we fall back to using timer
interrupts (as for the BIOS build).  Since timer interrupts are
disabled at TPL_CALLBACK, WaitForEvent() fails and no entropy can be
gathered.

Fix by dropping to TPL_APPLICATION while entropy gathering is enabled.
