[PATCH v6 16/28] mtd: spi-nor: swp: Cosmetic changes

[Miquel Raynal]

As a final preparation step for the introduction of CMP support, make
a few more cosmetic changes to simplify the reading of the diff when
adding the CMP feature. In particular, define "min_prot_len" earlier as
it will be reused and move the definition of the "ret" variable at the
end of the stack just because it looks better.
