Li Ming 1b3ed6c512 cxl/hdm: Fix potential infinite loop in __cxl_dpa_reserve() 
[ Upstream commit d4026a4462 ]

In __cxl_dpa_reserve(), it will check if the new resource range is
included in one of paritions of the cxl memory device.
cxlds->nr_paritions is used to represent how many partitions information
the cxl memory device has. In the loop, if driver cannot find a
partition including the new resource range, it will be an infinite loop.

[ dj: Removed incorrect fixes tag ]

Fixes: 991d98f17d ("cxl: Make cxl_dpa_alloc() DPA partition number agnostic")
