Fix UB in the locking code of context switching
...
The spin crate considers it UB to call force_write_unlock while there is
a threads trying to obtain a read lock on the same rwlock.
This also switches to the spinning_lot crate for the context rwlock as
it has support for a write guard keeping a reference to the rwlock using
an Arc instead of a reference.
