lib/edid.c: Avoid static analysis error for unused value

Within procedure cea_hdmi_block, the variable "b" is used as an index into
a buffer of EDID bytes. Each time it's used, it's incremented, but the last
increment is not used and is causing a static analysis error. Add a printk
at the end, using variable "b", to avoid the static analysis error.

BUG=b:112253891
TEST=Build and boot grunt.
