Christoph Hellwig c2389c0749 xfs: fix log recovery buffer allocation for the legacy h_size fixup
commit 45cf976008ddef4a9c9a30310c9b4fb2a9a6602a upstream.

Commit a70f9fe52d ("xfs: detect and handle invalid iclog size set by
mkfs") added a fixup for incorrect h_size values used for the initial
umount record in old xfsprogs versions.  Later commit 0c771b99d6
("xfs: clean up calculation of LR header blocks") cleaned up the log
reover buffer calculation, but stoped using the fixed up h_size value
to size the log recovery buffer, which can lead to an out of bounds
access when the incorrect h_size does not come from the old mkfs
tool, but a fuzzer.

Fix this by open coding xlog_logrec_hblks and taking the fixed h_size
into account for this calculation.

Fixes: 0c771b99d6 ("xfs: clean up calculation of LR header blocks")
