west.yml: update loramac-node to fix double promotion warning

Fixes implicit double promotion in RegionCommon.c.

The calculation is done with float variables. However, the floor
function is meant for double variables. floorf should be used instead.

The implicit double promotion leads to a warning/error if compiled with
LLVM in CI.
