scsi: ensure bdlen is initialized before use

Browse Source 
This fixes a false positive warning when building on GCC 7.2.1 with
CONFIG_COVERAGE=y.

bdlen is always initialized on the path where it can be used, but the
compiler seems to get confused when coverage is enabled, so zero out the
value at the top of the function.
