x86/entry: Add do_SYSENTER_32() prototype

The 32-bit system call entry points can be called on both 32-bit
and 64-bit kernels, but on the former the declarations are hidden:

arch/x86/entry/common.c:238:24: error: no previous prototype for 'do_SYSENTER_32' [-Werror=missing-prototypes]

Move them all out of the #ifdef block to avoid the warnings.
