usb: core: config: fix validation of wMaxPacketValue entries
The checks performed by commit aed9d65ac327 ("USB: validate
wMaxPacketValue entries in endpoint descriptors") require that initial
value of the maxp variable contains both maximum packet size bits
(10..0) and multiple-transactions bits (12..11). However, the existing
code assings only the maximum packet size bits. This patch assigns all
bits of wMaxPacketSize to the variable.
