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.
