i5000: Fix the fatal error handling
The fatal error channel bits point to a single channel, and not to a range of channels. Fix the code to properly report it, instead of printing messages like: kernel: EDAC MC0: INTERNAL ERROR: channel-b out of range (4 >= 4) Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
