[PATCH] drivers/scsi/aic94xx/aic94xx_hwi.c: add missing kfree

[Julia Lawall]

From: Julia Lawall <Julia.Lawall@xxxxxxx>

The free is not strictly necessary, because as long as the tc_index_array
field is not NULL, the free will performed by the calling context, in the
function asd_destroy_ha_caches.  But doing it here in this case, makes this
case consistent with the rest of the function.

Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx>

---
Alternatively, the frees could be dropped from the subsequent block of
error-handling code.
