When invoking block-export-add with some iothread and fixed-iothread=false, and changing the node's iothread fails, the error is supposed to be ignored.However, it is still stored in *errp, which is wrong. If a second error occurs, the "*errp must be NULL" assertion in error_setv() fails: qemu-system-x86_64: ../util/error.c:59: error_setv: Assertion `*errp == NULL' failed. So if fixed-iothread=false, we should ignore the error by passing NULL to bdrv_try_set_aio_context().
