lib/scatterlist: add sg_init_marker() helper
sg_init_marker initializes sg_magic in the sg table and calls
sg_mark_end() on the last entry of the table. This can be useful to
avoid memset in sg_init_table() when scatterlist is already zeroed out
For example: when scatterlist is embedded inside other struct and that
container struct is zeroed out
