sfc: process RX event inner checksum flags
Add support for RX checksum offload of encapsulated packets. This essentially just means paying attention to the inner checksum flags in the RX event, and if *either* checksum flag indicates a fail then don't tell the kernel that checksum offload was successful. Also, count these checksum errors and export the counts to ethtool -S. Test the most common "good" case of RX events with a single bitmask instead of a series of ifs. Move the more specific error checking in to a separate function for clarity, and don't use unlikely() there since we know at least one of the bits is bad.
