This commit fixes a regression to handle command line parameters of ubd.
With a simple line "./linux ubd0="./disk-ext4.img", it fails at
ubd_setup_common(). The commit adds additional checks to the variables
in order to properly parse the paremeters which previously worked.
Fixes: ef3ba87cb7c9 ("um: ubd: Set device serial attribute from cmdline")
