fix misaligned memory write access in abis_nm_ipaccess_rsl_connect()
Use memcpy() to avoid unaligned access, instead of writing through a
pointer cast to uint32_t. Problem spotted by address sanitizer:
abis_nm.c:2802:24: runtime error: store to misaligned address 0x7ffc95396706
for type 'uint32_t', which requires 4 byte alignment
0x7ffc95396706: note: pointer points here
