Subject: [PATCH] merge dst_discard in & out into one, this decrements the vmlinux image by 21 bytes under i386 arch.

From: Denis Cheng

thus the definition of dst_discard_in and dst_discard_out is the same,
we can define a dst_discard function and map the _in and _out to it,
this can reduce space in vmlinux.
