vboot2: pass const work buffers, and clarify min_offset output

When a work buffer is passed to a function, and duplicated inside that
function, allocations made against the duplicate are automatically
freed when the duplicate goes out of scope.  Make that explicit in the
comments.  And pass in const struct workbuf * instead of struct
workbuf *, to make it clear that the passed-in work buffer pointer is
not being altered by the function.

Also, comment that the value of min_offset becomes undefined if
vb2_verify_common_member() or vb2_verify_common_subobject() fails.
