[PATCH] uapi: net_dropmon: drop unused is_drop_point_hw macro

[RubenKelevra]

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.

Fixes: 4ea7e38696c7e ("dropmon: add ability to detect when hardware dropsrxpackets")
