Subject: [PATCH -mm] char, moxa: Make isabrds variable global.

 When CONFIG_MODULE=n and CONFIG_PCI=n, then variable
isabrds becomes unused variable. So place it outside
moxa_init solves this problem.

 We were warned by the following warning:

drivers/char/moxa.c: In function `moxa_init':
drivers/char/moxa.c:1012: warning: unused variable `isabrds'
