Free pgdir in setupkvm in case of mappages failure
...
There is a potential memory leak when mappages() fails inside setupkvm().
A call to freevm() is added in this case so as to reclaim the lost mapping pages.

Read curproc from cpu structure, but be careful because after a schedule event
...
myproc() points to a different thread.
myproc();
sched();
myproc(); // this proc maybe different than the one before sched
Thus, in a function that operates on one thread better to retrieve the
current process once at the start of the function.
