Commita780278472("drm/gem: Acquire reservation lock in drm_gem_{pin/unpin}()") moved locking the DRM object's dma reservation to drm_gem_pin(), but Lima's pin callback kept calling drm_gem_shmem_pin, which also tries to lock the same dma_resv, leading to a double lock situation. As was already done for Panfrost in the previous commit, fix it by replacing drm_gem_shmem_pin() with its locked variant.

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 reStructuredText 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.
