i2c: i2c_xilinx_axi: Fix for target mode interrupt handling

When a target was registered with the controller but a controller-mode
request was performed, the driver failed to mask the interrupts that
were occurring as a result of the controller-mode transfer, causing an
interrupt flood. Ensure that all interrupts not handled by target mode
are handled as potential controller-mode events and acknowledged
properly.
