Fixes the issue in #130182 where the variable `RemainingBitsInField` was used uninitialized, leading to undefined behavior in certain cases.
Although I wasn't able to reproduce the undefined behavior using Clang 18.1.8, I validated the fix with Valgrind while running the windows-Wpadded.cpp test.

@mikaelholmen @asb, could you please confirm if this resolves the issue on your end?
Thanks for your patience, and I hope the pin isn't too disruptive.
