drivers: hv: dxgkrnl: Fix build breaks when switching to 6.6 kernel due to removed uuid_le_cmp

uuid_le_cmp was removed and needs to be replaced by guid_equal. The
relevant upstream commits are:
1fb1ea0 "mei: Move uuid.h to the MEI namespace"
f5b3c34 "mei: Move uuid_le_cmp() to its only user"
5e6a517 "uuid: Decouple guid_t and uuid_le types and respective macros"
