[PATCH v2] staging: greybus: replace PTR_ERR() with %pe in error messages

[pavankumaryalagada@gmail.com]

From: Yalagada Pavan Kumar <pavankumaryalagada@gmail.com>

Use %pe to print error pointers directly and display their
error names.

Keep the other PTR_ERR() call because its return value is
needed for ret.

v2:
- Use %pe in the firmware management case, as suggested by Jeremy Clifton,
  to match the other cases.

v1: https://lore.kernel.org/outreachy/as0nhVbagZa8Birm@user/T/#t
