seqlock: Cure some more scoped_seqlock() optimization fails
Arnd reported an x86 randconfig using gcc-15 tripped over
__scoped_seqlock_bug(). Turns out GCC chose not to inline the
scoped_seqlock helper functions and as such was not able to optimize
properly.
[ mingo: Clang fails the build too in some circumstances. ]
