gfs2: journal flush threshold fixes and cleanup
Commit f07b35202148 ("GFS2: Made logd daemon take into account log demand") changed gfs2_ail_flush_reqd() and gfs2_jrnl_flush_reqd() to take sd_log_blks_needed into account, but the checks in gfs2_log_commit() were not updated correspondingly. Once that is fixed, gfs2_jrnl_flush_reqd() and gfs2_ail_flush_reqd() can be used in gfs2_log_commit(). Make those two helpers available to gfs2_log_commit() by defining them above gfs2_log_commit().
