[Bug 1893807] [NEW] Crash when launching windows qemu version from WSL2

[Jesús Sanz del Rey]

Public bug reported:

Version: 5.1.0
Command line from WSL2:
qemu-system-x86_64.exe -hdd /home/jesus/proyectos/RWivOS/bin/RELEASE/image.hdd 
-m 4G -smp 4 -machine q35 -debugcon stdio

OS: Windows 10(64 bits) from WSL2 Ubuntu 18.04

The error:
ERROR:/home/stefan/src/qemu/repo.or.cz/qemu/ar7/block.c:1325:bdrv_open_driver: 
assertion
 failed: (is_power_of_2(bs->bl.request_alignment))

The problem i'm seeing when i lauch from wsl2 only occurs when launched
with argument -hdd from WSL2, if i launch it from Windows pointing to
the WSL path where the file is stored works.

It occurs on other versions, i tried 4.1.0 too.
