Minggui Cao b048835c45 HV: fix bug "vmexit" cmd cause HV console hung ...

on KBL-NUC when input "vmexit" in hypervisor console,
the console or HV/SOS could be hung, the root cause is:
the log buffer is overflow for 8 CPU cores info.

to resolve the issue:
1. increase the shell log buffer size according to the
physical CPU max number
2. check the snprintf return value, if no buffer left,
just return.
