drm/i915: Fix calculation of rotated x and y offsets for planar formats
commit 3781bd6e7d64d5f5bea9fdee11ab9460a700c0e4 upstream.
Parameters tile_size, tile_width and tile_height were passed in the
wrong order to _intel_adjust_tile_offset() when calculating the rotated
offsets.
This doesn't fix any user visible bug, since for packed formats new
and old offset are the same and the rotated offsets are within a tile
before they are fed to _intel_adjust_tile_offset(). In that case, the
offsets are unchanged. That is not true for planar formats, but those
are currently not supported.
Fixes: 66a2d927cb0e ("drm/i915: Make intel_adjust_tile_offset() work for linear buffers")
