[LTP] [PATCH] nfs/nfs_lib.sh: Fix wrong getopts parameter handling

[Xiao Yang]

If nfs_lib.sh didn't use TST_OPTS and passed getopts parameter to
tst_net.sh which could only handle -6, it caused getopts error:
----------------------------------------------------------------
/opt/ltp/testcases/bin/nfs01: illegal option -- v
/opt/ltp/testcases/bin/tst_net.sh: line 37: ?: command not found
----------------------------------------------------------------

We use TST_OPTS and TST_PARSE_ARGS to fix this issue.
