Khazhismel Kumykov 2dd710d476 blk-throttle: check for overflow in calculate_bytes_allowed ...

Inexact, we may reject some not-overflowing values incorrectly, but
they'll be on the order of exabytes allowed anyways.

This fixes divide error crash on x86 if bps_limit is not configured or
is set too high in the rare case that jiffy_elapsed is greater than HZ.

Fixes: e8368b57c0 ("blk-throttle: use calculate_io/bytes_allowed() for throtl_trim_slice()")
Fixes: 8d6bbaada2 ("blk-throttle: prevent overflow while calculating wait time")
