This reverts commit fe0488aa13.
It caused messages like
amdgpu 0000:23:00.0: bo 000000007dce0b3e va 0x0000101800-0x000010181f conflict with 0x0000101800-0x0000101820
in dmesg, and eventually a Xorg crash while running piglit.
Evidently, such BOs can actually be re-imported by other means than via
a KMS handle.
Currently while exporting prime handle to fd read write access is
not granted. mmap fails because of this. mmap was not supported on
prime initially.
Here is link to related discussion

The mutex_unlock in bo_import should also cover bo refcount
