generic/765: Fix sysfs queue path for nvme partitions

This tests checks atomic write limits reported by statx() are same as
the ones reported by sysfs, however nvme partitions don't have the
/sys/block/nvme0n1p1 style entry and also use the namespace's queue
limits for atomic writes. This causes the test to fail because it
expects /sys/block/nvme0n*p* to be present.

Hence, use the new _sysfs_queue_path() helper to get the correct
atomic write limits

Also, fix a small typo (s/awu_min/awu_max) when printing awu limits to
seqres.full
