Summary: [patch] Exception in check_nt.c

Initial Comment:
routine CHECK_USEDDISKSPACE in check_nt.c do not handle correct unknown/missing drives.

# /usr/local/libexec/nagios/check_nt -H HOSTNAME -p 12489 -v USEDDISKSPACE -l d
Segmentation fault: 11 (core dumped)

# /usr/local/libexec/nagios/check_nt -H HOSTNAME -p 12489 -v USEDDISKSPACE -l e
Segmentation fault: 11 (core dumped)

# echo "None&4&d" | nc HOSTNAME 12489
UNKNOWN: Drive is not a fixed drive: d: (it is a cdrom drive)

# echo "None&4&e" | nc HOSTNAME 12489
UNKNOWN: Could not get free space for: e: e: reason: 3: The system cannot find the path specified.


#################################
snipped from the code:
#################################
        case CHECK_USEDDISKSPACE:
                        fetch_data (server_address, server_port, send_buffer);
/* --> no exception handling */
free_disk_space=atof(strtok(recv_buffer,"&"));
total_disk_space=atof(strtok(NULL,"&"));

The patch is maybe not optimal, but prevents segfault
