USB: usb-storage: increase max_sectors for tape drives
upstream commit: 5c16034d73da2c1b663aa25dedadbc533b3d811c
This patch (as1203) increases the max_sector limit for USB tape
drives. By default usb-storage sets max_sectors to 240 (i.e., 120 KB)
for all devices. But tape drives need a higher limit, since tapes can
and do have very large block sizes. Without the ability to transfer
an entire large block in a single command, such tapes can't be used.
This fixes Bugzilla #12207.
