xprtrdma: Create common scatterlist fields in rpcrdma_mw
It addresses a bug in:
commit d7a21c1bed54adcf96e1713019a6ad87e90fbbc3

AuthorDate: Mon May 2 14:42:12 2016 -0400

xprtrdma: Reset MRs in frwr_op_unmap_sync()
Which causes DMAR errors and an oops when using NFS/RDMA on
x86_64 systems where the iommu is enabled.
This was reported via IRC, I don't have the reporter's e-mail
address. I was able to reproduce the issue, and confirm that
564471d2f2f1 fixes the problem on v4.7.2.
(The actual fix is just two lines in that commit).

Hahahaha, the stable queue is over 300+ patches at the moment, please
give me a chance to at least apply the patches that are properly tagged
for stable kernels, and then I catch up on these "please add" patches.
Patience please...

No problem at all. I just didn't trust that the e-mail went through,
and I couldn't find a reliable list archive for stable@ to confirm.
