[PATCH] rtw88: coex: remove unnecessary variable and label

[samirweng1979 <samirweng1979@163.com>]

From: wengjianfeng <wengjianfeng@yulong.com>

In some funciton, the variable ret just used as return value,and
out label just return ret,so ret and out label are unnecessary,
we should delete these and use return true/false to replace.
