[PATCH next] io_uring/rsrc: Fix an IS_ERR() vs NULL bug in io_install_fixed_file()

[Dan Carpenter <dan.carpenter@linaro.org>]

The io_rsrc_node_alloc() function returns NULL on error, it doesn't
return error pointers.  Update the error checking to match.

Fixes: ead12caeb8ac ("io_uring/rsrc: get rid of per-ring io_rsrc_node list")
