buffer: return bool from grow_dev_folio()

Patch series "More buffer_head cleanups", v2.

The first patch is a left-over from last cycle.  The rest fix "obvious"
block size > PAGE_SIZE problems.  I haven't tested with a large block size
setup (but I have done an ext4 xfstests run).


This patch (of 7):

Rename grow_dev_page() to grow_dev_folio() and make it return a bool. 
Document what that bool means; it's more subtle than it first appears. 
Also rename the 'failed' label to 'unlock' beacuse it's not exactly
'failed'.  It just hasn't succeeded.
