UEAGLE: fix ueagle-atm Oops

The array of attribute passed to sysfs_create_group() must be
NULL-terminated.

The sysfs entries are created before the start of the modem state machine
to avoid to stop it in case of errors in sysfs creation.  Also
{destroy,create}_fs_entries are removed as they do nothing.
