stlink: fix max packet size for 8 bit R/W on stlink-v3

While ST internal documentation for STLINK-V3 reports that 8 bits
read/write commands handle 512 bytes of data, a firmware bug makes
it crashing on high data size.
This is fixed with firmware V3J6 (shipped together with V2J36).

Check for firmware version to use the proper data size.
