xemacpsif: fix compiler warnings

The compiler issues a couple of warnings as the Xilinx code omits to cast pointers ip_addr_t to the required ip4_addr_t or ip6_addr_t type.

Note, ip_addr_t can hold ip4_addr_t and ip6_addr_t. Therefore, the complaints by GCC are correct, but do not indicate a major bug.
