bdev/raid: remove random test case values

Browse Source 
For test setup only, each time a UT would run several params, like
the number of drives in the test, would be based on a random value
which is not optimal for UT. This patch just selects a reasonable
fixed values and uses them every time.

This can save up to 4 seconds per run depending on the values that
were randomly chosen (worst case) vs what is in this patch.

There is value in some read/write test cases in using different
strip sizes however. Enabling multiples values for the tests where
it adds value will come in following patches as will removal of
more random numbers like # of channels.
