[Xen-ia64-devel] [PATCH] fix compilation error.

[Isaku Yamahata <yamahata@xxxxxxxxxxxxx>]

[IA64]: fix compilation error.

BUILD_BUG_ON() was changed so that now BUILD_BUG_ON() can't be
used with symbol values.
Fortunately dom_fpswa_hypercall_patch() isn't performance critical
so replace BUILD_BUG_ON() with BUG_ON().
Fixed the wrong condition which has off-by-one bug.
