[PATCH] UEAGLE : cmv name bug (was cosmetic)

this patch correct a possible bug with cmv_name being static. If there
is 2 modems and the driver is scheduled when filling cmv_name this could
result with garbage in cmv_name. We allocate cmv_name on the stack but
with a small size in order to avoid that.
