phy: core: Fix error path in phy_create()
commit e73b49f1c4e75c44d62585cc3e5b9c7894b61c32 upstream.
Prevent resources from being freed twice in case device_add() call
fails within phy_create(). Also use ida_simple_remove() instead of
ida_remove() as we had used ida_simple_get() to allocate the ida.
