cxl/acpi: Fix a use-after-free in cxl_parse_cfmws()

In the Linux kernel, the following vulnerability has been resolved:

cxl/acpi: Fix a use-after-free in cxl_parse_cfmws()

KASAN and KFENCE detected an user-after-free in the CXL driver. This

happens in the cxl_decoder_add() fail path. KASAN prints the following

error:

BUG: KASAN: slab-use-after-free in cxl_parse_cfmws (drivers/cxl/acpi.c:299)

This happens in cxl_parse_cfmws(), where put_device() is called,

releasing cxld, which is accessed later.

Use the local variables in the dev_err() instead of pointing to the

released memory. Since the dev_err() is printing a resource, change the open

coded print format to use the %pr format specifier.
