drivers/net/cxgb3/cxgb3_main.c: prevent reading uninitialized stack memory

Fixed formatting (tabs and line breaks).

The CHELSIO_GET_QSET_NUM device ioctl allows unprivileged users to read
4 bytes of uninitialized stack memory, because the "addr" member of the
ch_reg struct declared on the stack in cxgb_extension_ioctl() is not
altered or zeroed before being copied back to the user.  This patch
takes care of it.
