mount.c: fix args parse error

argc number checking should be after getopt_long(), otherwise
we'll get follow result:
'''
~]# mount.nfs -V
usage: mount.nfs remotetarget dir [-rvVwfnsh] [-o nfsoptions]
options:
        -r              Mount file system readonly
        -v              Verbose
        -V              Print version
        -w              Mount file system read-write
        -f              Fake mount, do not actually mount
        -n              Do not update /etc/mtab
        -s              Tolerate sloppy mount options rather than fail
        -h              Print this help
        nfsoptions      Refer to mount.nfs(8) or nfs(5)
'''

after fix:
'''
~]# mount.nfs -V
mount.nfs: (linux nfs-utils 2.4.3)
