Subject: [PATCH 149/454] vcsm: Support for finding user/vc handle in memory
pool
vmcs_sm_{usr,vc}_handle_from_pid_and_address() were failing to find
handle if specified user pointer is not exactly the one that the memory
locking call returned even if the pointer is in range of map/resource.
So fixed the functions to match the range.
