fpga: stratix10-soc: Fix return value check in s10_ops_write_init()
commit 65ea840afd508194b0ee903256162aa87e46ec30 upstream.
In case of error, the function stratix10_svc_allocate_memory()
returns ERR_PTR() and never returns NULL. The NULL test in the
return value check should be replaced with IS_ERR().
