Subject: ocfs2: Revert 40bd62e to avoid regression in extended allocation
Revert 40bd62eb7fb844 ("fs/ocfs2/journal.h: add bits_wanted while
calculating credits in ocfs2_calc_extend_credits").
Unfortunately this change broke fallocate even if there is insufficient
disk space for the preallocation, which is a serious problem.
