[PATCH] drm/amdgpu: Fix typos in amdgpu_vm_bo_update comments

[Ding Yihan <dingyihan@uniontech.com>]

Fix spelling mistakes in the comment block within amdgpu_vm_bo_update().
Specifically, correct "contians" to "contains" and "WIRTEABLE" to
"WRITEABLE".

Additionally, improve the grammar, capitalization, and punctuation of
the comment for better readability.
