[PATCH 0/1] MR385: mountmgr.sys: Always set the return size from dhcp_request implementations.

[Tim Clem (＠tclem)]

The handler for IOCTL_MOUNTMGR_QUERY_DHCP_REQUEST_PARAMS allocates    
the return size on the stack and expects it to be valid after a
call to dhcp_request. The current early exits from the dbus and
Mac implementations do not always set it, sometimes resulting in
using a garbage return size.
