Christian König 6c4102522a drm/amdgpu: fix UVD contiguous CS mapping problem ...

commit 12f325bcd2411e571dbb500bf6862c812c479735 upstream.

When starting the mpv player, Radeon R9 users are observing
the below error in dmesg.

[drm:amdgpu_uvd_cs_pass2 [amdgpu]]
*ERROR* msg/fb buffer ff00f7c000-ff00f7e000 out of 256MB segment!

The patch tries to set the TTM_PL_FLAG_CONTIGUOUS for both user
flag(AMDGPU_GEM_CREATE_VRAM_CONTIGUOUS) set and not set cases.

v2: Make the TTM_PL_FLAG_CONTIGUOUS mandatory for user BO's.
v3: revert back to v1, but fix the check instead (chk).
