Fixes a bug where the kernel thinks the boot partition is still mounted
and it's unavailable for mounting in the rootfs
If you look at what the initramfs was doing before !5635, it was
explicitly umounting the boot partition from /boot in the initramfs and
then mounting it under /boot in the rootfs:
c45d7ec0a5/main/postmarketos-initramfs/init.sh (L87)
With this patch, we're now back to umounting /boot in the initramfs.
The second part of that original logic is now handled elsewhere now, and
that seems to be working OK.
The bug was reported here:
