[UINPUT] Allow EV_ABS to work in uinput.c

[Ian Campbell <icampbell@arcom.com>]

Hi,

uinput_alloc_device() is supposed to return the number of bytes read,
the value is returned to uinput_write() and from there to userspace. If
EV_ABS is set then it returns the value from uinput_validate_absbits()
instead, which is zero when everything is ok instead of the count.
