    net/utils: avoid unalign access g_tcp_connections_buffer
    
    the address is 0x3c270203, cause unaligned access usage Fault
    (gdb) p g_tcp_connections
    $1 = {pool = 0x3c270203 <g_tcp_connections_buffer> <error: Cannot access 
memory at address 0x3c270203>,
    prealloc = 8, dynalloc = 1, nodesize = -376, sem = {semcount = 32767, flags 
= 0 '\000',
    waitlist = {head = 0x0, tail = 0x0}}, freebuffers = {head = 0x0, tail = 
0x0}}
