Fix statement with no effect in linuxkpi's xarray.hHEADmain

When compiling the kernel with gcc 14, errors similar to the following
are emitted:

  sys/dev/cxgbe/iw_cxgbe/ev.c: In function 'c4iw_ev_handler':
  sys/compat/linuxkpi/common/include/linux/xarray.h:132:23: error: statement with no effect [-Werror=unused-value]
    132 |                 flags == 0; \
  sys/dev/cxgbe/iw_cxgbe/ev.c:274:17: note: in expansion of macro 'xa_unlock_irqrestore'
    274 |                 xa_unlock_irqrestore(&dev->cqs, flag);
        |                 ^~~~~~~~~~~~~~~~~~~~
  sys/compat/linuxkpi/common/include/linux/xarray.h:132:23: error: statement with no effect [-Werror=unused-value]
    132 |                 flags == 0; \
  sys/dev/cxgbe/iw_cxgbe/ev.c:283:17: note: in expansion of macro 'xa_unlock_irqrestore'

        |                 ^~~~~~~~~~~~~~~~~~~~

It looks like the intent of the "flags == 0" statement was to make the
'flags' macro argument not unused, but it still results in a warning.
Use the construct "(void)flags" instead.
