John Snow 176129552f mirror: clarify mirror_do_read return code ... mirror_do_read intends to return the number of sectors processed after the starting sector, without regard to how many sectors were processed before the starting sector due to alignment. Clean up the comments and code to hopefully illustrate this more clearly. This also fixes an issue in initialization where if the mirror buffer size is initialized to smaller than the number of sectors being requested for transfer, we report back an incorrectly large number to the caller.
