[PATCH next] initramfs_test: Fix NULL vs IS_ERR() bug in initramfs_test_data()

[Dan Carpenter <dan.carpenter@xxxxxxxxxx>]

The filp_open() function returns error pointers.  It never returns
NULL pointers.  Update the check to match.

Fixes: b6736cfccb58 ("initramfs_test: kunit tests for initramfs unpacking")
