[PATCH 50/55] drivers: hv: dxgkrnl: Fix build breaks when switching to 6.6 kernel due to removed uuid_le_cmp

[Eric Curtin]

From: Iouri Tarassov <iourit@xxxxxxxxxxxxxxxxxxx>

uuid_le_cmp was removed and needs to be replaced by guid_equal. The
relevant upstream commits are:
1fb1ea0d9cb8 "mei: Move uuid.h to the MEI namespace"
f5b3c341a46e "mei: Move uuid_le_cmp() to its only user"
5e6a51787fef "uuid: Decouple guid_t and uuid_le types and respective macros"
