quota: rename dquot_active() to inode_quota_active()

maillist inclusion
category: bugfix
bugzilla: 188812,https://gitee.com/openeuler/kernel/issues/I7E0YR
CVE: NA

Reference: https://www.spinics.net/lists/kernel/msg4844759.html

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

Now we have a helper function dquot_dirty() to determine if dquot has
DQ_MOD_B bit. dquot_active() can easily be misunderstood as a helper
function to determine if dquot has DQ_ACTIVE_B bit. So we avoid this by
renaming it to inode_quota_active() and later on we will add the helper
function dquot_active() to determine if dquot has DQ_ACTIVE_B bit.
