misc: mei: client.c: fix problem of return '-EOVERFLOW' in mei_cl_write
[ Upstream commit ee6236027218f8531916f1c5caa5dc330379f287 ]
Clang static analyzer complains that value stored to 'rets' is never
read.Let 'buf_len = -EOVERFLOW' to make sure we can return '-EOVERFLOW'.
Fixes: 8c8d964ce90f ("mei: move hbuf_depth from the mei device to the hw modules")
