fastboot: getvar: fix partition-size return value

Browse Source 
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].

Note that the function was already returning the proper size in bytes
for NAND devices (see struct part_info details).
