OHCI: Fix array out of bounds issue
If using a USB hub, a request outside the array size can occur
Original line:
https://github.com/hathach/tinyusb/blob/ffb257ac17f162bc5a4c26596d7a1e954db98aa5/src/portable/ohci/ohci.h#L162
It can happen in a few places but one such example is here:
https://github.com/hathach/tinyusb/blob/ffb257ac17f162bc5a4c26596d7a1e954db98aa5/src/portable/ohci/ohci.c#L460
ie. if HUB address is 5, this would be an array index out of bounds on control endpoints as `CFG_TUH_DEVICE_MAX+1` is only 5.
This fix just includes num of hubs in the reserve array size.
Fixing locally fixed this issue.
