[Bug] Crystal Ridge - 4.12 - x86, pmem: Fix cache flushing for iovec

Bug description:
Description:
Commit 11e63f6d920d added cache flushing for unaligned writes from an iovec,
covering the first and last cache line of a >= 8 byte write and the first cache
line of a < 8 byte write. But an unaligned write of 2-7 bytes can still cover
two cache lines, so make sure we flush both in that case.
Target Kernel:4.12
Target Release: 17.10
