Subject: [PATCH] ANDROID: Fix CRC error with iommu_* functions

In commit 1edce43f4799 ("iommu/dma: Trace bounce buffer usage when
mapping buffers"), a new #include file was added, which now properly
defines some structures that were previously not defined, which messes
with the CRC of some iommu_* functions.

Resolve this by only including the new include file if crc generation is
not happening.

Bug: 161946584
Fixes: 1edce43f4799 ("iommu/dma: Trace bounce buffer usage when mapping buffers")
Change-Id: I57aab13f789b4afe38a5bbb9b3798eab78c0df3e
