mpt3sas: Ensure the connector_name string is NUL-terminated
We blindly trust the hardware to give us NUL-terminated strings, which
is a bad idea because it doesn't always do that. For example:
[ 481.184784] mpt3sas_cm0: enclosure level(0x0000), connector name( \x3)
In this case, connector_name is four spaces. We got lucky here because
the 2nd byte beyond our character array happens to be a NUL. Fix this by
explicitly writing '\0' to the end of the string to ensure we don't run
off the edge of the world in printk().
