gpu: host1x: Use a signed return type for do_relocs()

elfring · thierryreding · commit 341917fe2b62 · 2016-03-16T13:45:44.000+01:00
The return type "unsigned int" was used by the do_relocs() function
despite the fact that it will eventually return a negative error code.
Use a signed integer instead to accomodate for error codes.

This issue was detected by using the Coccinelle software.
