MSM: fix access type length and validation
This patch fixes three issues with access type:
- SMACK_ACCESS_TYPE_LENGHT -> SMACK_ACCESS_TYPE_LENGTH
- Changed the value of SMACK_ACCESS_TYPE_LENGTH from 5 to 6.
- String length was calculated with unsafe 'strlen()'. Changed to
use strlen(type, SMACK_LABEL_LENGTH + 1) instead.
