wlan: Avoid buffer overflow.
scnprintf returns the number of characters
which are actually written in the buffer.
Currently there is no check, while filling
buffer. Hence a situation might arise where
the len is greater than the sizeof of buffer.
Latter on this buffer is copied to user space
through api copy_to_user and since the len
is greater than buffer size, buffer over-flow
would occur. As a part of fix, make sure that
buffer over doesn't occur.
