docs/core-api: Remove possibly confusing sub-headings from Bit Operations
The recent commit 81d2c6f81996 ("kasan: support instrumented bitops combined with generic bitops"), split the KASAN instrumented bitops into separate headers for atomic, non-atomic and locking operations. This was done to allow arches to include just the instrumented bitops they need, while also using some of the generic bitops in asm-generic/bitops (which are automatically instrumented). The generic bitops are already split into atomic, non-atomic and locking headers. This split required an update to kernel-api.rst because it included include/asm-generic/bitops-instrumented.h, which no longer exists. So now kernel-api.rst includes all three instrumented headers to get the definitions for all the bitops. When adding the three headers it seemed sensible to add sub-headings for each, ie. "Atomic", "Non-atomic" and "Locking". The confusion is that test_bit() is (and always has been) in non-atomic.h, but is documented elsewhere (atomic_bitops.txt) as being atomic. So having it appear under the "Non-atomic" heading is possibly confusing. Probably test_bit() should move from bitops/non-atomic.h to atomic.h, but that has flow on effects. For now just remove the newly added sub-headings in the documentation, so we at least aren't adding to the confusion about whether test_bit() is atomic or not.
