[v2,1/2] syscalls/{quotactl04, statx05}.c: Replace extra_opts[] with fs_opts[]

extra_opts[] is to store the options which are passed after device name
(e.g. fs-size: mkfs -t ext4 /dev/sda1 <fs-size>) so perfer to use
fs_opts[] for quotactl04.c and statx05.c.

Also add a hint to doc/test-writing-guidelines.txt.

Hi,

This is a simple patch set so I pushed it.

Thanks,
