Keith Busch c32d5491c8 block: fix infinite loop for invalid zone append 
[ Upstream commit b82d9fa257cb3725c49d94d2aeafc4677c34448a ]

Returning 0 early from __bio_iov_append_get_pages() for the
max_append_sectors warning just creates an infinite loop since 0 means
success, and the bio will never fill from the unadvancing iov_iter. We
could turn the return into an error value, but it will already be turned
into an error value later on, so just remove the warning. Clearly no one
ever hit it anyway.
