[PATCH] remove gratuitous space in airo module description

Currently the modinfo looks like:

description:    Support for Cisco/Aironet 802.11 wireless ethernet                    cards.  Direct support for ISA/PCI/MPI cards and support               for PCMCIA when used with airo_cs.

Arguably, it should be cut at the end of the first sentence.
This at least makes it somewhat more legible.
