Alan Somers 0425e01683 According to devctl(4), clients must read events whole; they may not
piece them together from multiple reads().  It's as if /dev/devctl is
a datagram device instead of a stream device.  However, devd's
internal buffer was too small (1025 bytes) to read an entire
ereport.fs.zfs.checksum event (variable, up to ~1300 bytes).  This
commit enlarges the buffer to 8k.
