dpaa2-eth: Remove preempt_disable() from seed_pool()
According to the comment, the preempt_disable() statement is required due to synchronisation in napi_alloc_frag(). The awful truth is that local_bh_disable() is required because otherwise the NAPI poll callback can be invoked while the open function setup buffers. This isn't unlikely since the dpaa2 provides multiple devices. The usage of napi_alloc_frag() has been removed in commit 27c874867c4e9 ("dpaa2-eth: Use a single page per Rx buffer") which means that the comment is not accurate and the preempt_disable() statement is not required. Remove the outdated comment and the no longer required preempt_disable().
