[PATCH v14 07/15] eal: change rte_exit() output to match rte_log()

[Stephen Hemminger]

The rte_exit() output format confuses the timestamp and coloring
options. Change it to use be a single line with proper prefix.

Before:
[     0.006481] EAL: Error - exiting with code: 1
  Cause: [     0.006489] Cannot init EAL: Permission denied

After:
[     0.006238] EAL: Error - exiting with code: 1
[     0.006250] EAL: Cause - Cannot init EAL: Permission denied
