[PATCH 2/2] xfs/157: do not drop necessary mkfs options

[Zorro Lang <zlang@kernel.org>]

To give the test option "-L oldlabel" to _scratch_mkfs_sized, xfs/157
does:

  MKFS_OPTIONS="-L oldlabel $MKFS_OPTIONS" _scratch_mkfs_sized $fs_size

but the _scratch_mkfs_sized trys to keep the $fs_size, when mkfs
fails with incompatible $MKFS_OPTIONS options, likes this:

  ** mkfs failed with extra mkfs options added to "-L oldlabel -m rmapbt=1" by test 157 **
  ** attempting to mkfs using only test 157 options: -d size=524288000 -b size=4096 **

but the "-L oldlabel" is necessary, we shouldn't drop it. To avoid
that, we give the "-L oldlabel" to _scratch_mkfs_sized through
function parameters, not through global MKFS_OPTIONS.
