[PATCH] blk_rq_map_user_iov: fix error override

During stress tests by syzkaller on the sg driver the block layer infrequently returns EINVAL. Closer inspection shows the block layer was trying to return ENOMEM (which is much more understandable) but for some reason overroad that useful error. Patch below does not show this (unchanged) line:

[PATCH v2] nl80211: take RCU read lock when calling ieee80211_bss_get_ie()

Linux 4.15-rc8

Ok, another week has gone by, and here's the promised rc8. I'm still hoping that this will be the last rc, despite all the Meltdown and Spectre hoopla. But we will just have to see, it obviously requires this upcoming week to not come with any huge surprises. The patches aren't huge, but
