bFLT triggers accel/tcg/user-exec.c:505: page_set_flags: Assertion `have_mmap_lock()' failed.

As of v9.1.0-rc2 when running tests/avocado/load_bflt.py I get:

./qemu-arm -L test_arm_bflt.LoadBFLT.test_stm32/lib/ test_arm_bflt.LoadBFLT.test_stm32/bin/busybox
qemu-arm: ../../accel/tcg/user-exec.c:505: page_set_flags: Assertion `have_mmap_lock()' failed.
Aborted (core dumped)

backtrace:
