Prepare to mark sensitive kernel structures for randomization by making
sure they're using designated initializers. These were identified during
allyesconfig builds of x86, arm, and arm64, with most initializer fixes
extracted from grsecurity.
For these cases, terminate the list with { }, which will be zero-filled,
instead of undesignated NULLs.

Without CONFIG_DEBUG_FS, we run into a link error:
drivers/scsi/qedi/qedi_iscsi.o: In function `qedi_ep_poll':
qedi_iscsi.c:(.text.qedi_ep_poll+0x134): undefined reference to `do_not_recover'
drivers/scsi/qedi/qedi_iscsi.o: In function `qedi_ep_disconnect':

qedi_fw.c:(.text.qedi_tmf_work+0x3b4): undefined reference to `do_not_recover'
This defines the symbol as a constant in this case, as there is no way to
set it to anything other than zero without DEBUG_FS. In addition, I'm renaming
it to qedi_do_not_recover in order to put it into a driver specific namespace,
as "do_not_recover" is a really bad name for a kernel-wide global identifier
when it is used only in one driver.
