[PATCH] ext4: fix __ext4_xattr_set_credits()

[Tahsin Erdogan]

__ext4_xattr_set_credits() calculates journal credits needed for a
set xattr operation. Currently, credits needed for quota updates are
added only if ea_inode feature is enabled which is wrong. Fix this by
moving quota related additions to above ea_inode feature check.
