pds_fwctl: Remove the use of dev_err_probe()

Logging messages that show some type of "out of memory" error are generally
unnecessary as there is a generic message and a stack dump done by the
memory subsystem. These messages generally increase kernel size without
much added value[1].

The dev_err_probe() doesn't do anything when error is '-ENOMEM'. Therefore,
remove the useless call to dev_err_probe(), and just return the value
instead.
