tsc: calculate elapsed ticks using saturating_sub
...
RDTSC readouts might not actually be monotonically increasing due to
desynchronization between CPU cores, so checked_sub was causing a kernel
panic.

Fix possible UB in rmm::init.
...
I tested compiling the kernel with a more recent rustc, and this
triggered UB. Don't know for sure why there was an invalid entry passed
to the kernel, but it did.

Allow writing messages to debug: without preserving them in sys:log

This would allow logd to write all received log messages to debug:
without causing an infinite loop when it at the same time reads all
messages in sys:log.
