locking: Make rwsem_assert_held_write_nolockdep() build with PREEMPT_RT=y
The commit cited below broke the build for PREEMPT_RT because
rwsem_assert_held_write_nolockdep() passes a struct rw_semaphore but
rw_base_assert_held_write() expects struct rwbase_rt. Fixing the type alone
leads to the problem that WARN_ON() is not found because bug.h is missing.
In order to resolve this:
- Keep the assert (WARN_ON()) in rwsem.h (not rwbase_rt.h)
- Make rwsem_assert_held_write_nolockdep() do the implementation
specific (rw_base) writer check.
- Replace the "inline" with __always_inline which was used before.
Fixes: f70405afc99b1 ("locking: Add rwsem_assert_held() and rwsem_assert_held_write()")
