[PATCH 02/10] mtd-utils: nandwrite: Comment, style fixups

[Brian Norris]

Comment on "blockalign" default value is incorrect; it only defaults
to a 1x multiplier of the actual block size. Perhaps this is a relic
of early NAND where all block sizes were 16KB?

Reformatted a multi-line comment.

Changed separete "if" statements to a combined "if-else-if" since they
were logically combinable. Should have no effect on results with minor
effect on efficiency.
