"link_elf: symbol msleep undefined"...

This just bit me, the attached fixes seem to work for me (I can load the
drivers into the kernel).
It turns out that the __FreeBSD_version cpp conditional is incorrect for
7.0-RELEASE shipping systems. The key observation was that on line 76 of
linux_compat.c, msleep() is in fact undefined.
The only cam I have at the moment is the Trust Spacec@m 380 which is not
supported by the ported ov511 driver, I'm waiting on more units arriving.
