[PATCH] fastboot: getvar: fix partition-size return value

[Gary Bisson <gary.bisson@boundarydevices.com>]

The size returned by 'getvar partition-size' should be in bytes, not in
blocks as fastboot uses that value to generate empty partition when
running format [1].

Hi,

Another test was to run 'fastboot getvar partition-size:system' on a
shipping Android phone, it will give you the size in bytes as well.

Regards,
Gary
