cciss: Don't check h->busy_initializing in cciss_open(). 

Don't check h->busy_initializing in cciss_open().  Open won't be
called before things are ready, but h->busy_initializing won't be
unset until after the initial rebuild_lun_table is finished.  But,
to read the partitions, cciss_open will be called for each logical
drive during rebuild_lun_table.  If cciss_open checks h->busy_initializing,
then the reading of the partition information during the initial
rebuild_lun_table will fail, which is especially bad news if it
happens to be your boot device.
