Fix following compiling errors:
In file included from ../drivers/cxl/core/pmu.c:10:
../drivers/cxl/core/core.h: In function ‘cxl_decoder_detach’:
../drivers/cxl/core/core.h:65:1: error: no return statement in function returning non-void [-Werror=return-type]
 }

make[6]: *** Waiting for unfinished jobs....
  CC [M]  drivers/infiniband/core/verbs.o

Fixes: b3a88225519c ("cxl/region: Consolidate cxl_decoder_kill_region() and cxl_region_detach()")
