Ok, was able to fix this by doing a LOOKUP sequence in a separate compound
followed by GETFH then in the compound that tests SAVEFH/RESTOREFH, just do
PUTFH that saved FH.

Things could be a lot smoother as discussed on IRC if the initialization
stored away env.home_fh.

Then with some work, this test could be simplified to:

SEQUENCE, PUTFH(env.home_fh), OPEN, GETFH, SAVEFH, PUTFH(env.home_fh),
RESTOREFH, CLOSE

Note that that GETFH is not actually used by this test, but presumably
open_create_op() would produce:

PUTFH(env.home_fh), OPEN, GETFH

Instead of what it currently does:

PUTROOTFH, LOOKUP..., OPEN, GETFH

The new branch is here:
