拉取/合并请求描述:(PR description)

为什么提交这份PR (why to submit this PR)
1.使用mmap时,当传入一个非常大的地址时,offset会计算得到一个值,又因为传入的地址错误,rc会得到错误码,结合offset会得到一个很奇怪的值。
2.执行setpgrp后,再使用getpgrp无法得到创建的group的值
你的解决方案是什么 (what is your solution)
1.修改mmap的返回方式
2.添加group = lwp_pgrp_create(process);执行后的一些行为
请提供验证的bsp和config (provide the config and bsp)
