Memory leak in server's read_process_memory handler

[Ken Thomases]

The read_process_memory handler in server/process.c allocates a  
buffer for the reply data.  In the case where the read_process_memory 
() function succeeds, that buffer is set into the reply.  However, in  
the case where read_process_memory() fails, that buffer is leaked.

Changelog:
     Fixed leak: free buffer when read_process_memory() fails
