Tom Caputi 35050ef39e Fix integer overflow of ZTOI(zp)->i_generation
The ZFS on-disk format stores each inode's generation ID as a 64
bit number on disk and in-core. However, the Linux kernel's inode
is only a 32 bit number. In most places, the code handles this
correctly, but the cast is missing in zfs_rezget(). For many pools,
this isn't an issue since the generation ID is computed as the
current txg when the inode is created and many pools don't have
more than 2^32 txgs.

For the pools that have more txgs, this issue causes any inode with
a high enough generation number to report IO errors after a call to
"zfs rollback" while holding the file or directory open. This patch
simply adds the missing cast.
