io_uring: Fix uninitialized variable up.resv
The variable up.resv is not initialized and is being checking for a
non-zero value in the call to _io_register_rsrc_update. Fix this by
explicitly setting the variable to 0.
Addresses-Coverity: ("Uninitialized scalar variable)"
Fixes: c3bdad027183 ("io_uring: add generic rsrc update with tags")
