Changing the switch() statement to symbolic constants made
the compiler (at least clang-9, did not check gcc) notice that
there is one enum value that is not handled here:
block/t10-pi.c:62:11: error: enumeration value 'T10_PI_TYPE0_PROTECTION' not
handled in switch [-Werror,-Wswitch]
Add another case for the missing value and do nothing there
based on the assumption that the code was working correctly
already.
