dhcp: fix warning messages when calling strtoip() 

With the removal of dupicate strtoip in patch "dhcp: Remove duplicated
strtoip()" (commit 896e31da2c), we get
following warnings messages:

dhcp.c: In function ‘dhcpv4’:
dhcp.c:215:16: warning: pointer targets in passing argument 1 of ‘strtoip’ differ in signedness [-Wpointer-sign]
   if (!strtoip(dhcp_tftp_name, (uint8_t *)&dhcp_tftp_ip)) {
                ^
In file included from dhcp.c:51:0:
../netapps/args.h:20:5: note: expected ‘const char *’ but argument is of type ‘int8_t * {aka signed char *}’
 int strtoip(const char *, char[4]);
     ^
dhcp.c:215:32: warning: pointer targets in passing argument 2 of ‘strtoip’ differ in signedness [-Wpointer-sign]
   if (!strtoip(dhcp_tftp_name, (uint8_t *)&dhcp_tftp_ip)) {
                                ^
In file included from dhcp.c:51:0:
../netapps/args.h:20:5: note: expected ‘char *’ but argument is of type ‘uint8_t * {aka unsigned char *}’
 int strtoip(const char *, char[4]);
     ^

There were unnecessary typecasts which could be removed by declaring
dhcp_tftp_name and dhcp_filename. Along with this, change the dns_get_ip
signature as well to reduce typecast.
