[LTP] [PATCH 1/1] shell: Fix handling default parameters in tst_mkfs()

[Petr Vorel]

fixes regression when testing df01.sh

Dash does not like shifting more than possible:
/opt/ltp/testcases/bin/df01.sh: 291: shift: can't shift that many

Fixes: 465faf47f ("shell: Use $TST_FS_TYPE and $TST_DEVICE in tst_mkfs()")

Hi,

don't like checking $# twice, but don't see right now way to do it
simpler.

Sorry for introducing regression.

Kind regards,
Petr
