EDAC/{skx_common,i10nm}: Rename rrl_mode to rrl_source_type

The RRL (Retry Read error Log) values describe where an error was logged
from (first/last read and scrub/demand), not an operating mode.

Rename rrl_mode to rrl_source_type and "modes" to "sources" to better
reflect their meaning and improve code readability.

No functional changes intended.
