[PATCH] gpib: gpio: use %pe to print error pointer

[Chen Jung Ku]

In allocate_gpios(), the error from gpiod_get_index() is printed using
PTR_ERR() and the %ld format specifier. Use the %pe format specifier
and pass the error pointer directly instead.

This allows the symbolic error name (e.g. -EBUSY) to be printed rather
than a bare number, making the log easier to read.

No functional change.
