Some callers handle SYS_INFO_ALL_BT themselves before calling sys_info().
Add a helper that strips that bit without turning an all_bt only mask into
a kernel_sys_info fallback.

You also want a getter with check

bool sysinfo_is_all_bt_enabled(...,  *si_mask)

where *si_mask is the result of READ_ONCE() that you keep as implementation
detail inside this helper.

Ah, sorry, I have thought that the mask is part of sysinfo implementation.
Disregard my above comment, it can't be done without also supplying the pointer
to the original one, which makes no sense.
