btrfs: resurrect btrfs_crc32c()
Commit 9678c54388b6 ("btrfs: Remove custom crc32c init code") removed
the btrfs_crc32c() function, because it was a duplicate of the crc32c()
library function we already have in the kernel.
Resurrect it as a shim wrapper over crc32c() to make following
transformations of the checksumming code in btrfs easier.
Also provide a btrfs_crc32_final() to ease following transformations.
