[PATCH] jbd2: remove redundant function jbd2_journal_has_csum_v2or3_feature

[Eric Biggers <ebiggers@kernel.org>]

From: Eric Biggers <ebiggers@google.com>

Since commit dd348f054b24 ("jbd2: switch to using the crc32c library"),
jbd2_journal_has_csum_v2or3() and jbd2_journal_has_csum_v2or3_feature()
are the same.  Remove jbd2_journal_has_csum_v2or3_feature() and just
keep jbd2_journal_has_csum_v2or3().
