drm/amdgpu/userq: ignore duplicate BO locks when counting wait fences

amdgpu_userq_wait_count_fences() calls drm_exec_init() without
DRM_EXEC_IGNORE_DUPLICATES. When the same GEM object appears more than
once across the read/write BO handle lists submitted by userspace,
drm_exec_lock_obj() returns -EALREADY the second time it locks that
object, which aborts the fence-counting pass instead of treating the
repeat as a no-op.

Add DRM_EXEC_IGNORE_DUPLICATES so duplicate objects are silently
skipped on the second lock attempt.
