Revert "USB: serial: make bulk_out_size a lower limit"
commit bc4b1f486fe69b86769e07c8edce472327a8462b upstream.
This reverts commit 5083fd7bdfe6760577235a724cf6dccae13652c2.
A bulk-out size smaller than the end-point size is indeed valid. The
offending commit broke the usb-debug driver for EHCI debug devices,
which use 8-byte buffers.
