qemu-io: Don't leak pattern file in error path
qemu_io_alloc_from_file() needs to close the pattern file even if some
error occurred.
Setting f = NULL in the success path and checking it for NULL in the
error path isn't strictly necessary at this point, but let's do it
anyway in case someone later adds a 'goto error' after closing the file.
