c1ick ec580bc520 zfs: add bounds checking to zil_parse (#16308) 
Make sure log record don't stray beyond valid memory region.

There is a lack of verification of the space occupied by fixed members
of lr_t in the zil_parse.

We can create a crafted image to trigger an out of bounds read by
following these steps:
    1) Do some file operations and reboot to simulate abnormal exit
       without umount
    2) zil_chain.zc_nused: 0x1000
    3) First lr_t
       lr_t.lrc_txtype: 0x0
       lr_t.lrc_reclen: 0x1000-0xb8-0x1
       lr_t.lrc_txg: 0x0
       lr_t.lrc_seq: 0x1
    4) Update checksum in zil_chain.zc_eck

Fix:
Add some checks to make sure the remaining bytes are large enough to
hold an log record.
