Darrick J. Wong 9f0f659ea9 iomap: error out on file IO when there is no inline_data buffer 
[ Upstream commit 6a96fb653b ]

Return IO errors if an ->iomap_begin implementation returns an
IOMAP_INLINE buffer but forgets to set the inline_data pointer.
Filesystems should never do this, but we could help fs developers (me)
fix their bugs by handling this more gracefully than crashing the
kernel.
