[PATCH 1/2] btrfs: inline enable_quota helper in test 301

The enable_quota helper in btrfs/301 takes a mode argument ('n', 's',
or anything else) to switch between "no quota", "simple quota", and
"full quota" enable.  Only the simple-quota path is ever exercised by
this test, so the dispatch is dead weight and the indirection just
obscures the actual btrfs command being run.

Inline the two call sites to call 'btrfs quota enable --simple'
directly and drop the helper.
