When using the vvfat driver with a directory that contains too many files,
QEMU currently crashes. This can be triggered like this for example:
mkdir /tmp/vvfattest
cd /tmp/vvfattest
for ((x=0;x<=513;x++)); do mkdir $x; done
qemu-system-x86_64 -drive \
file.driver=vvfat,file.dir=.,read-only=on,media=cdrom
Seems like read_directory() is changing the mapping->path variable. Make
sure we use the right pointer instead.
