    efi: Fix debugobjects warning on 'efi_rts_work'

    [ Upstream commit ef1491e791308317bb9851a0ad380c4a68b58d54 ]

    The following 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.

was incorrectly applied to v4.19.41 and causes lockdep complaints for
the onstack efi_rts_work being initialised by INIT_WORK().
