uapi: bitops: use UAPI-safe variant of BITS_PER_LONG again
commit 11fcf368506d347088e613edf6cd2604d70c454f upstream.
Commit 1e7933a575ed ("uapi: Revert "bitops: avoid integer overflow in GENMASK(_ULL)"")
did not take in account that the usage of BITS_PER_LONG in __GENMASK() was
changed to __BITS_PER_LONG for UAPI-safety in
commit 3c7a8e190bc5 ("uapi: introduce uapi-friendly macros for GENMASK").
BITS_PER_LONG can not be used in UAPI headers as it derives from the kernel
configuration and not from the current compiler invocation.
When building compat userspace code or a compat vDSO its value will be
incorrect.
Switch back to __BITS_PER_LONG.
