fs: remove sb->s_mode 

JIRA: https://issues.redhat.com/browse/RHEL-1516
Conflicts: drop change on f2fs which isn't enabled on rhel9

commit 81b1fb7d17c0110df839e13468ada9e99bb6e5f4

    fs: remove sb->s_mode

    There is no real need to store the open mode in the super_block now.
    It is only used by f2fs, which can easily recalculate it.
