Removed BUG_ON statements from gm20b_pbdma_acquire_val, as condition could never be true. The only overflow that can happen is in nvgpu_safe_mult_u64. Compute exponent by shifting timeout (in units of 1024 ns) until it fits into mantissa. This removes the need to compute most significant bits, and allows using hw definitions for mantissa and exponent max values.
