Phil Turnbull 3eb6b89a4e wifi: wilc1000: validate number of channels
commit 0cdfa9e6f0915e3d243e2393bfa8a22e12d553b0 upstream.

There is no validation of 'e->no_of_channels' which can trigger an
out-of-bounds write in the following 'memset' call. Validate that the
number of channels does not extends beyond the size of the channel list
element.
