A REMAP op is composed of 3 VMA's - unmap, prev map, and next map. When op_execute fails with -EAGAIN we need to update the local VMA pointer to the current op state and then repin the VMA if it is a userptr. Fixes a failure seen in xe_vm.munmap-style-unbind-userptr-one-partial.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
