libmem_get_sector_size is a helper function that returns the sector size for an address within a specified geometry.

start — A pointer to the start address of the geometry desribed by geometry.

geometry — A pointer to the NULL terminated geometry description.

p — A pointer to the address to determine the sector information of.

libmem_get_sector_size returns — The size of the sector or 0 if the sector cannot be found.
