fix up ext2_fs.h for userspace after reservations backport
In commit a686cd898bd999fd026a51e90fb0a3410d258ddb: "Val's cross-port of the ext3 reservations code into ext2." include/linux/ext2_fs.h got a new function whose return value is only defined if __KERNEL__ is defined. Putting #ifdef __KERNEL__ around the function seems to help, patch below.
