[PATCH zfsonlinux] update submodule to 2.4.3 and refresh patches

[Stoiko Ivanov]

drop patch 11 which is included in 2.4.3

The changeset between 2.4.2 and 2.4.3 is not too large - notable
commits (from quickly looking through `git log`):
* 1821ca2db ("ZVOL: Add encryption key check for block cloning") could
  affect users who enabled both blockcloning and encryption manually
* 50697dc93 ("Fix log vdev removal issues")
*  97117686d ("Remove parent ZIO from dbuf_prefetch()") - performance
   improvment with recordsize 4k of 5-10%
* 3a897c4e8 ("Avoid flushing unrelated NFS exports on snapshot unmount")
  fixes flushing all exports on each snapshot umount, which looks like
  it causes quite some performance degradation on NFS-servers using
  ZFS)
* 63a0ff6cd ("nvpair: Check for un-terminated strings in packed nvlist")

a few commits are general defensive clean-ups and robustness
improvments (fixing lock-order reversals, preventing overflows in
integer conversion, properly initiallizing variables)

I minimally tested the changes with 2 virtual PVE-nodes with storage
replication and container guests.

-Subject: [PATCH] spl_kvmalloc: remove __GFP_COMP before calling vmalloc()
-
-In cb1833023 we stopped using it for KM_VMEM allocations, since its not
-a valid flag for vmalloc(). However, there's a fallback path for
-non-KM_VMEM allocations to use vmalloc(), and we need to remove
-__GFP_COMP there too to avoid a warning.
