fix section mismatch warning in lib/swiotlb.c
kbuild spits outs following warning on a defconfig x86_64 build: WARNING: swiotlb.o - Section mismatch: reference to .init.text:swiotlb_init from __ksymtab between '__ksymtab_swiotlb_init' (at offset 0xa0) and '__ksymtab_swiotlb_free_coherent' This warning happens because the function swiotlb_init is marked __init and EXPORT_SYMBOL(). A 'git grep swiotlb_init' showed no users in drivers/ so remove the EXPORT_SYMBOL.
