[PATCH v5 2/9] irqchip/al-fic: use %pe to print init error

[Eliav Farber <farbere@amazon.com>]

al_fic_init_dt() logs PTR_ERR(fic) with %lu when al_fic_wire_init()
fails. PTR_ERR() returns a signed long, so printing it with an
unsigned format specifier turns a negative error code into a large
positive value, making it harder to read.

Pass fic to %pe directly instead of unwrapping it with PTR_ERR()
first. %pe accepts the ERR_PTR-encoded pointer itself and prints a
symbolic error name (e.g. -EINVAL) when one is known, falling back
to the plain decimal value otherwise.
