[PATCH] cciss: increase number of commands on controller
Remove #define NR_CMDS and replace it w/hba[i]->nr_cmds. Most Smart Array
controllers can support up to 1024 commands but the E200 family can only
support 128. To prevent annoying "fifo full" messages we define nr_cmds on a
per controller basis by adding it the product table.
