The new commit 'drm/i915/gem: Don't fault on presumed_offset write-back' [1]

reverts commit '97a37c919f62 ("drm/i915/gem: Ignore readonly failures when
updating relocs")'

And this blows up exec_reloc concurrent tests that uses
mprotect(reloc, sz, PROT_READ); [2]

I'm not sure if this is a real use case though...
