[PATCH] bcm43xx-softmac: Fix an off-by-one condition in handle_irq_noise

An assert statement near the start of handle_irq_noise in the softmac
version of bcm43xx_main.c is there to protect against out of bound
addressing using variable bcm->noisecalc.nr_samples. The arrays in
question have a dimension of 8, thus the value must be < 8.
