Changed lfs_crc to match more common API

Browse Source 
In looking at the common CRC APIs out there, this seemed the most
common. At least more common than the current modified-in-place pointer
API. It also seems to have a slightly better code footprint. I'm blaming
pointer optimization issues.

One downside is that lfs_crc can't report errors, however it was already
assumed that lfs_crc can not error.
