cxl/pci: Clean up cxl_mem_get_partition_info()
Commit 0b9159d0ff21 ("cxl/pci: Store memory capacity values") missed
updating the kernel-doc for 'struct cxl_mem' leading to the following
warnings:
./scripts/kernel-doc -v drivers/cxl/cxlmem.h 2>&1 | grep warn
drivers/cxl/cxlmem.h:107: warning: Function parameter or member 'total_bytes' not described in 'cxl_mem'
drivers/cxl/cxlmem.h:107: warning: Function parameter or member 'volatile_only_bytes' not described in 'cxl_mem'

drivers/cxl/cxlmem.h:107: warning: Function parameter or member 'partition_align_bytes' not described in 'cxl_mem'
drivers/cxl/cxlmem.h:107: warning: Function parameter or member 'active_volatile_bytes' not described in 'cxl_mem'
drivers/cxl/cxlmem.h:107: warning: Function parameter or member 'active_persistent_bytes' not described in 'cxl_mem'
drivers/cxl/cxlmem.h:107: warning: Function parameter or member 'next_volatile_bytes' not described in 'cxl_mem'
drivers/cxl/cxlmem.h:107: warning: Function parameter or member 'next_persistent_bytes' not described in 'cxl_mem'
Also, it is redundant to describe those same parameters in the
kernel-doc for cxl_mem_get_partition_info(). Given the only user of that
routine updates the values in @cxlm, just do that implicitly internal to
the helper.
