Subject: [PATCH 1/1] staging: greybus: fw-core: use %pe for error printing

Use the %pe printk format specifier to print error codes as symbolic
names (e.g., -ENOMEM) instead of numeric values. This improves
readability of error logs.

Issue identified by coccicheck using the ptr_err_to_pe.cocci script.
