UBI: fix two issues in the ubi.mtd MODULE_PARM_DESC
Fix two issues introduced before:
- The parameter format string was missing the enable_fm and
need_resv_pool tokens introduced in an earlier commit.
- The bad-block reservation note was misplaced after Example 5
instead of after Example 3. It was misplaced due to an earlier patch.
Fixes: 83ff59a06663 ("UBI: support ubi_num on mtd.ubi command line")
