USB: android: Don't set can_stall module param to true

USB Mass storage driver uses can_stall module param to stall bulk-in USB
endpoint in multiple cases where some of UDC doesn't clear halt condition
reliably and waits for RESET from host to clear this condition. DWC
controller doesn't require this feature as it is able to handle halt
condition properly. Hence don't set can_stall module param to true. Also
it has been observed that USB mass storage driver violates specification
by explicitly halting USB bulk-in endpoint which causes enumeration issue
with connected host.
