Subject: [PATCH] rseq: Delete duplicate if statement in
 rseq_virt_userspace_exit()

This if statement is indented weirdly.  It's a duplicate and doesn't
affect runtime (beyond wasting a little time).  Delete it.

This was introduced in commit 32034df66b5f ("rseq: Switch to TIF_RSEQ if
supported") but it doesn't cause a bug, so there is no Fixes tag.
