Subject: posix-timers: Fix nanosleep_copyout() for CONFIG_COMPAT_32BIT_TIME

From: Arnd Bergmann <a...@arndb.de>

[ Upstream commit 0fe2795516b9e1c59b58b02bdf8658698117ec4e ]

Commit b5793b0d92c9 added support for building the nanosleep compat system
call on 32-bit architectures, but missed one change in nanosleep_copyout(),
which would trigger a BUG() as soon as any architecture is switched over to
use it.

Use the proper config symbol to enable the code path.

Fixes: Commit b5793b0d92c9 ("posix-timers: Make compat syscalls depend on 
CONFIG_COMPAT_32BIT_TIME")
