[PATCH i-g-t] i915/gem_pread, gem_pwrite: Exercise using ourselves as the buffer

[Chris Wilson]

If we caused a fault on a GEM buffer while in the middle of trying to
write/read into that buffer, we could conceivably deadlock (e.g.
recursing on struct_mutex if we are not careful). Exercise these cases
by supplying a fresh mmap to pread/pwrite in both non-overlapping and
overlapping copies.
