[PATCH v4 11/31] x86,fs/resctrl: Rename struct rdt_mon_domain and rdt_hw_mon_domain

[Tony Luck <tony.luck@intel.com>]

These structures have generic names, but are only used for L3 monitor
events.

Rename:
rdt_mon_domain		-> rdt_l3_mon_domain
rdt_hw_mon_domain	-> rdt_hw_l3_mon_domain

Signed-off-by: Tony Luck <tony.luck@intel.com>
