[PATCH v3 2/8] tools/xl: Correct the help information and exit code of the dt-overlay command

[Henry Wang <xin.wang2@xxxxxxx>]

Fix the name mismatch in the xl dt-overlay command, the
command name should be "dt-overlay" instead of "dt_overlay".
Add the missing "," in the cmdtable.

Fix the exit code of the dt-overlay command, use EXIT_FAILURE
instead of ERROR_FAIL.

Fixes: 61765a07e3d8 ("tools/xl: Add new xl command overlay for device tree 
overlay support")
