[PATCH] efi: Fix debugobjects warning on efi_rts_work

[Waiman Long]

The commit 9dbbedaa6171 ("efi: Make efi_rts_work accessible to efi
page fault handler") converted efi_rts_work from an auto variable to a
global variable. However, when submitting the work, INIT_WORK_ONSTACK()
was still used causing the following complaint from debugobjects:

ODEBUG: object 00000000ed27b500 is NOT on stack 00000000c7d38760,
but annotated.

Change the macro to just INIT_WORK() to eliminate the warning.

Fixes: 9dbbedaa6171 ("efi: Make efi_rts_work accessible to efi page fault handler")
