Martin K. Petersen d09c05aa35 scsi: core: Handle devices which return an unusually large VPD page count 
Peter Schneider reported that a system would no longer boot after
updating to 6.8.4.  Peter bisected the issue and identified commit
b5fc07a5fb ("scsi: core: Consult supported VPD page list prior to
fetching page") as being the culprit.

Turns out the enclosure device in Peter's system reports a byteswapped
page length for VPD page 0. It reports "02 00" as page length instead
of "00 02". This causes us to attempt to access 516 bytes (page length
+ header) of information despite only 2 pages being present.

Limit the page search scope to the size of our VPD buffer to guard
against devices returning a larger page count than requested.
