The null_blk configfs file 'features' provides a string that lists available null_blk features for userspace programs to reference. The string is defined as a long constant in the code, which tends to be forgotten for updates. It also causes checkpatch.pl to report "WARNING: quoted string split across lines". To avoid these drawbacks, generate the feature string on the fly. Refer to the ca_name field of each element in the nullb_device_attrs table and concatenate them in the given buffer. Also, sorted nullb_device_attrs table elements in alphabetical order. Of note is that the feature "index" was missing before this commit. This commit adds it to the generated string.
