[PATCH v4 04/12] cper: Return actual bytes written by DIMM location helpers

[Pierre Gondois]

Use scnprintf() instead of snprintf() to return the actual chars
written to the buffer in:
- cper_dimm_err_location()
- cper_dimm_err2_location()

This allows to make the buffer progress correctly in
the caller function.
