From: Ben Hutchings ben@decadent.org.uk
Commit ea08dc5191d9 "fs/binfmt_elf.c: fix bug in loading of PIE binaries", which was a backport of commit a87938b2e246 upstream, added a new failure path to load_elf_binary().
Before commit 19d860a140be "handle suicide on late failure exits in execve() in search_binary_handler()", load_elf_binary() wass responsible for sending a fatal signal to the task in case of an error after flushing the old executable. Add that to the new failure path.
