Input: ucb1400_ts - IRQ probe fix

Browse source 
The UCB1400 driver IRQ probe code fails to find an interrupt if all
the interrupts in the range 0-31 are nonprobe-able. This patch
removes the check of the return value so interrupts above 31 can be
detected.

Tested on InHand Fingertip4 PXA270 board.
