gpu: nvgpu: Cast negative int to u32 before shift

Browse Source 
A shift of a negative number is undefined; so to work around
said warning simply cast to a u32 first. In this case the
resulting operation should be ok since the sign bits are
maintained when the 32 bit negative integer is shifted into
a 24 bit negative integer.
