cxl: Use %pe to print error pointers

Use the %pe printk format specifier to report error pointers directly
instead of printing PTR_ERR() as a long value.  A failed dport addition
then reports -EBUSY rather than -16, which is easier to follow when
tracing port and region setup with dynamic debug enabled.

Convert the five affected sites in drivers/cxl/core/port.c and
drivers/cxl/core/region.c.  PTR_ERR() uses in return statements are
unaffected and left unchanged.

drivers/cxl was scanned in full; these are the only conversion
candidates.

No functional change intended.
