Sergey Bugaev cfdbb712fb Kernel: Fix failing in can_read()/can_write() 
Now that the SystemMonitor queries which open files can be read and written to,
having can_read()/can_write() unconditionally call ASSERT_NOT_REACHED() leads
to system crashes when inspecting the WindowServer.

Instead, just return true from can_read()/can_write() (indicating that the
read()/write() syscalls should not block) and return -EINVAL when trying to
actually read from or write to these devices.
