f2fs: fix to align to section for fallocate() on pinned file
[ Upstream commit e1175f02291141bbd924fc578299305fcde35855 ]
Now, fallocate() on a pinned file only allocates blocks which aligns
to segment rather than section, so GC may try to migrate pinned file's
block, and after several times of failure, pinned file's block could
be migrated to other place, however user won't be aware of such
condition, and then old obsolete block address may be readed/written
incorrectly.
To avoid such condition, let's try to allocate pinned file's blocks
with section alignment.
