fs: quota: fix array-index-out-of-bounds bug by passing correct argument to vfs_cleanup_quota_inode()

When dquot_resume() was last updated, the argument that got passed
to vfs_cleanup_quota_inode was incorrectly set.

If type = -1 and dquot_load_quota_sb() returns a negative value,
then vfs_cleanup_quota_inode() gets called with -1 passed as an
argument, and this leads to an array-index-out-of-bounds bug.

Fix this issue by correctly passing the arguments.
