[PATCH] ext4: use __ext4_get_inode_loc() from ext4_write_inode()

[Curt Wohlgemuth]

Fix for no-journal ext4_write_inode() code path: ensure in_mem is 0 on call
to __ext4_get_inode_loc()

In the no-journal case, ext4_write_inode() simply gets the BH for the inode
table block and calls sync_dirty_buffer() on it.  But it doesn't copy the
in-memory inode contents to the on-disk format on the BH.  So it *must* not
cause the in_mem parameter to __ext4_get_inode_loc() to be 1, which it will
be if it uses ext4_get_inode_loc().

Applied to the ext4 patch queue.
