Max Reitz 8573823f3b block/export: Conditionally ignore set-context error 
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().

Fixes: f51d23c80a
       ("block/export: add iothread and fixed-iothread options")
