[PATCH 2/7] monitor: Mask flags from attribute identifier

Certain flags (for example, NLA_F_NESTED) are ORed with the netlink
attribute type identifier prior to being sent on the wire. Such flags
need to be masked off and not taken into consideration when attribute
type is being compared against known values.
