fastboot: change default sparse limit to disabled 

Change the default sparse limit to disabled to prevent resparsing files
unless the bootloader or user specifies a sparse limit.  Some
bootloaders issue an erase before every flash command, which causes
earlier parts of the downloaded image to get erased.
