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.
