nfs/localio: remove alignment size checking in nfs_is_local_dio_possible

[ Upstream commit f50d0328d02fe38ba196a73c143e5d87e341d4f7 ]

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).
