[PATCH] GPU-host1x: Use a signed return type for do_relocs()

[PATCH] GPU-host1x: Use a signed return type for do_relocs()

[SF Markus Elfring]

The return type "unsigned int" was used by the do_relocs() function
despite of the aspect that it will eventually return a negative error code.
Improve this implementation detail by deletion of the type qualifier then.

This issue was detected by using the Coccinelle software.
