MDEV-24167 fixup: srw_lock_debug for SUX_LOCK_GENERIC

Browse source 
srw_lock_debug::have_rd(), srw_lock_debug::have_wr():
For SUX_LOCK_GENERIC (no futex based synchronization primitives),
we cannot check if the underlying srw_lock is held by us.

Thanks to Dmitry Shulga for pointing out this build failure.
