nfs/localio: remove alignment size checking in nfs_is_local_dio_possible 



This check to ensure dio_offset_align isn't larger than PAGE_SIZE is
no longer relevant (older iterations of NFS Direct was allocating
misaligned head and tail pages but no longer does, so this check isn't
needed).

Fixes: c817248f ("nfs/localio: add proper O_DIRECT support for READ and WRITE")
