r24132 (https://dev.openwrt.org/ticket/8308) introduced the -n flag for
mtd, which is supposed to bypass the erase step. It appears that the
logic used to do this is backwards, and that erasing will actually be
bypassed unless -n is given. Lots and lots of things will break.
(no_erase) needs to change to (!no_erase).
The indentation in the original patch was also wrong (it used spaces in
a file that uses tabs), and since a new |if| block was introduced, its
contents ought to be reindented too.
