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.
