[PATCH v2 04/11] docs: dell_rbu.txt: fix location of request_firmware

[Mauro Carvalho Chehab]

commit 5d6d1ddd2730 ("firmware: move firmware loader into its own directory")
and other commits renamed the old firmware_class.c file and split it
into separate files, but documentation was not changed accordingly,
causing Sphinx errors.

Fixes for other files were already applied but dell_rbu.txt remains
pointing to the old location.

    Also after updating the BIOS image a user mode application needs to execute
    code which sends the BIOS update request to the BIOS. So on the next reboot
