scsi: aacraid: Fix udev inquiry race condition

commit f4e8708d3104437fd7716e957f38c265b0c509ef upstream.

When udev requests for a devices inquiry string, it might create multiple
threads causing a race condition on the shared inquiry resource string.

Created a buffer with the string for each thread.
