函数名称：Check whether the passed remaining file @buf_size is large enough to contain* a patch of the indicated @sh_psize (and also whether this size does not* exceed the per-family maximum). @sh_psize is the size read from the section* header.

函数原型：static unsigned int __verify_patch_size(u8 family, unsigned int sh_psize, size_t buf_size)

返回类型：unsigned int
