If a scsi host driver specifies .cmd_len in it's scsi_host_template, a driver's
private command pool is needed. scsi_find_host_cmd_pool() will locate it, but
scsi_alloc_host_cmd_pool() isn't saving the pool address in the host template.
This will result in an access error when the host is removed.
Avoid the problem by saving the address of a new allocated command pool where
it is expected and delete it again when the pool is destroyed.
I don't really like the double pointer passing - just NULLing out the
pointer in the caller where needed seems cleaner.
I wanted to avoid to spread this, but I don't mind doing it. V4 is
coming...
