btrfs-progs: tests: don't check subpage related warnings for simple fsck tests

For fsck tests, we check the subpage warnings for each type 1 test, but
such type 1 tests are mostly read-only tests, and one of the test will
trigger new subpage related warnings (fsck/018).

For subpage related warnings, what we really care are write operations,
including mkfs, btrfs-convert and repair, not those read-only tests.

So skip the subpage warning check for fsck type 1 tests to prevent false
alert of later more strict subpage warnings.
