gfs2-utils: Bug 481762 - No longer able to mount GFS volume with noatime,noquota options
    
    A previously committed patch to allow NOATIME and NODIRATIME
    http://git.fedorahosted.org/git/cluster.git?p=cluster.git;a=commitdiff;h=ea8e447f55864271a645a0b5ab32fb383bb8ad96
    was broken. It didn't allow any other extra mount option to be used in
    conjunction with noatime or nodiratime. Mount would fail with an
    'invalid argument' error. This patch fixes the incorrect parsing that
    causes the above error.
