[PATCH v3 4/4] xfs: clean up xfs_inactive() error handling, kill VN_INACTIVE_[NO]CACHE

[Brian Foster <bfoster@xxxxxxxxxx>]

The xfs_inactive() return value is meaningless. Turn xfs_inactive()
into a void function and clean up the error handling appropriately.
Kill the VN_INACTIVE_[NO]CACHE directives as they are not relevant
to Linux.
