db: fix AGI ops definition in CRC type table

The wrong buffer ops structure was added to the AGI field of the
type table when initially committed. This was not noticed because it
only affects manually setting the type of a buffer from xfs_db. e.g

xfs_db> agi 0
xfs_db> p
.....
crc = 0xbc58d757 (correct)
.....
xfs_db> fsb 2
xfs_db> type agi
Metadata CRC error detected at block 0x10/0x1000
xfs_db>

This is because (trimmed for clarity):

Breakpoint 1, xfs_verifier_error:
(gdb) bt
#0  xfs_verifier_error
#1  xfs_agfl_read_verify
#2  set_iocur_type
#3  type_f
#4  main

It's clear that the wrong verifier is being run (AGFL, not AGI).
The fix is simple.
