Subject: [PATCH] drm: Fix missing kernel-doc parameter descriptions in drm_gem_shmem_init()

The kernel test robot reported missing parameter documentation in
drm_gem_shmem_init(), triggering warnings during documentation builds:

WARNING: ./drivers/gpu/drm/drm_gem_shmem_helper.c:104 function parameter 'shmem' not described in 'drm_gem_shmem_init'
WARNING: ./drivers/gpu/drm/drm_gem_shmem_helper.c:104 function parameter 'size' not described in 'drm_gem_shmem_init'

Add missing @shmem and @size descriptions to fix the kernel-doc issues
and ensure the documentation is complete

Fixes: e3f4bdaf2c5b ("drm/gem/shmem: Extract drm_gem_shmem_init() from drm_gem_shmem_create()")
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202508040518.ZISc9nPg-lkp@intel.com
