[LTP] [PATCH 1/1] nfs_lib: Fix fsid randomisation

[Petr Vorel]

Testing nfs with multiple versions (-v, i.e. nfs0*_06 - testing with
nfs06.sh) nfs_lib.sh exports multiple different directories all with the
same fsid= value, which is not supposed to work (and breaks on older
nfs-utils).

Therefore increase fsid value for each loop.

Hi,

fsid check is not required, but added to prevent another false positive
in the future.

Thanks Neil!

Kind regards,
Petr
