Description

Several improvements were suggested in LU-8186 for the text displayed in the /proc/fs/lustre/llite/.../extents_stats* files. The relevant text occurs multiple times in lustre/llite/lproc_llite.c:

seq_puts(seq, "disabled\n write anything in this file to activate, then 0 or \"[D/d]isabled\" to deactivate\n");

The following changes should be made to all occurrences of the text:

• Use single quotes to avoid the need for escapes.
• Simplify the message by only mentioning "disabled" with lower case, and silently continue to accept "Disabled".
• Use a | to separate the two options to be consistent with accepted usage.
• Replace "in this file" with "to this file"
