[LTP] [PATCH 1/1] tst_test.sh: Print help ASAP

[Petr Vorel]

There is no need to run setup before printing help.

Before this change root was required for network tests also for -h:

    $ PATH="$lb:$PATH" nfs01 -h
    nfs01 1 TCONF: Must be super/root for this test!

And with root setup was run:

	# PATH="$lb:$PATH" nfs07.sh -h
	nfs07 1 TINFO: initialize 'lhost' 'ltp_ns_veth2' interface
	nfs07 1 TINFO: add local addr 10.0.0.2/24
	nfs07 1 TINFO: add local addr fd00:1:1:1::2/64
	nfs07 1 TINFO: initialize 'rhost' 'ltp_ns_veth1' interface
	nfs07 1 TINFO: add remote addr 10.0.0.1/24
	nfs07 1 TINFO: add remote addr fd00:1:1:1::1/64
	nfs07 1 TINFO: Network config (local -- remote):
	nfs07 1 TINFO: ltp_ns_veth2 -- ltp_ns_veth1
	nfs07 1 TINFO: 10.0.0.2/24 -- 10.0.0.1/24
	nfs07 1 TINFO: fd00:1:1:1::2/64 -- fd00:1:1:1::1/64
	-t x    Socket type, tcp or udp, default is udp
	-v x    NFS version, default is '3'
	-n x    Create x files and x directories, default is 5000
	-h      Prints this help
	-i n    Execute test n times

Now help is simply printed:

    $ PATH="$lb:$PATH" nfs01 -h
    -t x    Socket type, tcp or udp, default is udp
    -v x    NFS version, default is '3'
    -6      IPv6 tests
    -h      Prints this help
    -i n    Execute test n times
