libavfilter/x86/vf_gblur: correct the order of loop step

The problem was caused by if the width of the processed block minus 1 is a multiple of the aligned number the instruction jle .bscale_scalar would skip the Optimized Loop Step, which will lead to an incorrect sampling when specifying steps more than 1. Move the Optimized Loop Step after .bscale_scalar to ensure the loop step is enabled.
