apm821xx: switch out kernel's CRC32 method
This patch replaces the OpenWrt' favoured CRC32 Sarwate algorithm with the kernel recommended SLICE8 CRC32 version. This change alone lifted btrfs writes from 40 MiB/s to 54 MiB/s on my My Book Live (SLICE4 managed 48 MiB/s). Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
