mm/compaction: really limit compact_unevictable_allowed to 0 and 1
The proc file `compact_unevictable_allowed' should allow 0 and 1 only, the
`extra*' attribues have been set properly but without
proc_dointvec_minmax() as the `proc_handler' the limit will not be
enforced.
Use proc_dointvec_minmax() as the `proc_handler' to enfoce the valid
specified range.
