IB/uverbs: Use get_unused_fd_flags(O_CLOEXEC) instead of get_unused_fd()
The macro get_unused_fd() is used to allocate a file descriptor with
default flags. Those default flags (0) can be "unsafe": O_CLOEXEC must
be used by default to not leak file descriptor across exec().
Replace calls to get_unused_fd() in uverbs with calls to
get_unused_fd_flags(O_CLOEXEC). Inheriting uverbs fds across exec()
cannot be used to do anything useful.
Based on a patch/suggestion from Yann Droneaud <ydroneaud@opteya.com>.
