Get rid of EXTEND_DISKSIZE flag of ext4_get_blocks_handle(). This seems to be a
relict from some old days and setting disksize in this function does not make
much sence. Currently it was set only by ext4_getblk(). Since the parameter
has some effect only if create == 1, it is easy to check by grepping through
the sources that the three callers which end up calling ext4_getblk() with
create == 1 (ext4_append, ext4_quota_write, ext4_mkdir) do the right thing and
set disksize themselves.

The patch should be against ext4 patch queue now. Ted, will you merge it
please? Thanks.
