[PATCH] ocfs2: fix uninitialized variable in ocfs2_dio_wr_get_block()

[Dan Carpenter <dan.carpenter@oracle.com>]

The callers assume that "*fsdata" is set on the success path, but
that's not necessarily true on this path.

Please review this one EXTRA CAREFULLY.  It's from static analysis and
the truth is I'm not 100% sure it's correct.  I'm also not sure that
it's a complete fix.

Especially, please review how this is called from ocfs2_write_begin()
to make sure that this doesn't break anything.
