net: Move NetClientState.info_str to dynamic allocations
The info_str field of the NetClientState structure is static and has a size
of 256 bytes. This amount is often unclaimed, and the field itself is used
exclusively for HMP "info network".
The patch translates info_str to dynamic memory allocation.
This action is also allows us to painlessly discard usage of this field
for backend devices.
