[WCNCR00151641] misc: fix output format in iwpriv ver

[Description]
Fix output format in iwpriv ver

Misbehavior:
Version output result may look like this line.
"N9  tailer version 7668_trunk (YYYYMMDDhhmmsse�) info 4:E1"
The datecode should be "YYYYMMDDhhmmss[f/e/a]" (15 bytes). So, the pending
garbled text is not necessary and may cause the screen cleared in minicom.

Solution:
Avoid snprintf working improperly, exactly print 15 bytes only.
