md: remove the 'super' sysfs attribute from devices in an 'md' array
Exposing the binary blob which is the md 'super-block' via sysfs doesn't really fit with the whole sysfs model, and ever since commit 8118a859dc7abd873193986c77a8d9bdb877adc8 ("sysfs: fix off-by-one error in fill_read_buffer()") it doesn't actually work at all (as the size of the blob is often one page). (akpm: as in, fs/sysfs/file.c:fill_read_buffer() goes BUG) So just remove it altogether. It isn't really useful.
