[PATCH] usr/gen_init_cpio.c: remove unnecessary "if"

[Cong Ding <dinggnu@gmail.com>]

usr/gen_init_cpio.c: remove unnecessary "if"

if it goes to fail, dname isn't allocated; otherwise, it is allocated
successfully. so we just free memory when it doesn't fail.

this patch also fix a trival trailing space warning by checkpatch
