Commit 4ea7e38696c7 ("dropmon: add ability to detect when hardware drops rx packets") introduced is_drop_point_hw, but the symbol was never referenced anywhere in the kernel tree and is currently not used by dropwatch. I could not find, to the best of my abilities, a current out-of-tree user of this macro. The definition also contains a syntax error in its for-loop, so any project that tried to compile against it would fail. Removing the macro therefore eliminates dead code without breaking existing users.
