[PATCH][cciss] Fix a small memory leak in the cciss driver

[Jesper Juhl]

Hello,

There's a memory leak in the cciss driver.

in alloc_cciss_hba() we may leak sizeof(ctlr_info_t) bytes if a 
call to alloc_disk(1 << NWD_SHIFT) fails.
This patch should fix the issue.

 Spotted by the Coverity checker.
 Compile tested only.
