ext4: make trim/discard optional (and off by default)

(cherry picked from commit 5328e635315734d42080de9a5a1ee87bf4cae0a4)

It is anticipated that when sb_issue_discard starts doing
real work on trim-capable devices, we may see issues.  Make
this mount-time optional, and default it to off until we know
that things are working out OK.
