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Remove the outdated comment and the no longer required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().
