fstab: remove discard from metadata partition

Browse Source 
USB drives typically don't support TRIM. The USB DISK 3.0 in use explicitly
rejects it (EXT4-fs: mounting with discard option, but the device does not
support discard). Every ext4 journal commit on sda8 was attempting a TRIM,
adding latency that stalled jbd2/sda8-8 and caused Watchdog kills.
