BUG/MEDIUM: quic: Floating point exception in cubic_root()

It is illegal to call my_flsl() with 0 as parameter value. It is a UB.
This leaded cubic_root() to divide values by 0 at this line:

  x = 2 * x + (uint32_t)(val / ((uint64_t)x * (uint64_t)(x - 1)));

Thank you to Tristan971 for having reported this issue in GH #1808
and Willy for having spotted the root cause of this bug.

Must follow any cubic for QUIC backport (2.6).
