Patrick McHardy 61808c2bbb [PATCH] cciss: fix use-after-free in cciss_init_one
free_hba() sets hba[i] to NULL, the dereference afterwards results in this
crash.  Setting busy_initializing to 0 actually looks unnecessary, but I'm
not entirely sure, which is why I left it in.

cciss: controller appears to be disabled
Unable to handle kernel NULL pointer dereference at virtual address 00000370
