Working on the poisoned memory recovery mechanisms with David
Hildenbrand, it appeared that the file hole punching done with
the memory discard functions are missing the file offset value
fd_offset to correctly modify the right file location.

I'm not sure that guest_memfd would use a non zero fd_offset, but I'm
also modifying the ram_block_discard_guest_memfd_range() function to
include this fallocate use case too.

The fix is checkpatch.pl clean
make check runs fine on both ARM and x86
