ext4: make ext4_abort() use __ext4_error()

mainline inclusion
from mainline-v5.11-rc1
commit 014c9caa
category: bugfix
bugzilla: 50839
CVE: NA

-----------------------------------------------

The only difference between __ext4_abort() and __ext4_error() is that
the former one ignores errors=continue mount option. Unify the code to
reduce duplication.
