cnss: Fix a boundary check bug in cnss prealloc driver

Browse source 
Currently the driver gives a memory slot only if its size is greater
than the memory requested by the caller. This will waste a bigger slot
if the memory requested is equal to the slot size. Hence fix it by
adding the equal check when a memory slot is requested.
