cxl/region: decrement ->nr_targets on error in cxl_region_attach()
The ++ needs a match -- on the clean up path. If the p->nr_targets
value gets to be more than 16 it leads to uninitialized data in
cxl_port_setup_targets().
drivers/cxl/core/region.c:995 cxl_port_setup_targets() error: uninitialized symbol 'eiw'.
