make sure we free the context for the pmap in pmap_destroy(). 

this usually isn't necessary since we freed it earlier in pmap_remove_all(),
but since uvmspace_free() is now called in the context of the exiting
process, a new context might be allocated if uvm_unmap_detach() decides
to sleep (since cpu_switch() will allocate a new context when it switches
back to the exiting process).
