usb: properly detect empty mass storage media reader
When a USB card reader is empty, it will return "Not Ready - medium not
present" as Key Code Qualifier. In that situation, it's useless waiting
for the full timeout since the result won't change until the user
inserts a card.
U-Boot mass storage returns empty mass storage devices with a size of 0,
skip them in the VBoot devices enumeration.

BUG=None
TEST=On Link, run without a MMC card.
