Maciej Grochowski a133e3caf8 ntb: ntb_hw_switchtec: Fix shift-out-of-bounds for 0 mw lut 
[ Upstream commit 186615f885 ]

Number of MW LUTs depends on NTB configuration and can be set to zero,
in such scenario rounddown_pow_of_two will cause undefined behaviour and
should not be performed.
This patch ensures that rounddown_pow_of_two is called on valid value.
