Subject: [PATCH 474/478] features/locks: posixlk-clear-lock should set error
 as EINTR

Problem:
fuse on receiving interrupt for setlk sends clear-lock "fop"
using virtual-getxattr. At the moment blocked locks which are
cleared return EAGAIN errno as opposed to EINTR errno

Fix:
Return EINTR errno.
