Subject: [PATCH] efi/libstub: x86: fix unused-variable warning

The only users of these got removed, so they also need to be
removed to avoid warnings:

arch/x86/boot/compressed/eboot.c: In function 'setup_efi_pci':
arch/x86/boot/compressed/eboot.c:117:16: error: unused variable 'nr_pci' [-Werror=unused-variable]
unsigned long nr_pci;
^~~~~~
arch/x86/boot/compressed/eboot.c: In function 'setup_uga':
arch/x86/boot/compressed/eboot.c:244:16: error: unused variable 'nr_ugas' [-Werror=unused-variable]
unsigned long nr_ugas;
^~~~~~~

Fixes: 2732ea0d5c0a ("efi/libstub: Use a helper to iterate over a EFI handle array")

Oops

Acked-by: Ard Biesheuvel <[email protected]>

or I can add it to my next batch of EFI changes at the end of the week.
