e2fsck: do not attempt to discard if -n was specified

If '-n' option is specified there should be no changes made to the file
system hence we should not attempt to discard the file system. This
commit adds a check into the e2fsck_discard_blocks() condition so it skip
discard if E2F_OPT_NO flag is set.
