Subject: [PATCH AUTOSEL 6.7 35/58] drm/nouveau: nvkm_gsp_radix3_sg() should use nvkm_gsp_mem_ctor()

From: Timur Tabi <ttabi@...dia.com>

[ Upstream commit 34e659f34a7559ecfd9c1f5b24d4c291f3f54711 ]

Function nvkm_gsp_radix3_sg() uses nvkm_gsp_mem objects to allocate the
radix3 tables, but it unnecessarily creates those objects manually
instead of using the standard nvkm_gsp_mem_ctor() function like the
rest of the code does.
