[PATCH] bcm43xx-d80211 (try 2): Fix an off-by-one condition in handle_irq_noise

[PATCH] bcm43xx-d80211 (try 2): Fix an off-by-one condition in handle_irq_noise

[Larry Finger]

An assert statement near the start of handle_irq_noise in the d80211 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. This patch mirrors the one
submitted earlier for the softmac version of bcm43xx.
