Revert "binfmt_elf, coredump: Log the reason of the failed core dumps"
This reverts commit fb97d2eb542faf19a8725afbd75cbc2518903210.
The logging was questionable to begin with, but it seems to actively
deadlock on the task lock.
"On second thought, let's not log core dump failures. 'Tis a silly place"
because if you can't tell your core dump is truncated, maybe you should
just fix your debugger instead of adding bugs to the kernel.
