[PATCH 1/6] block: Include error-injection.h for ALLOW_ERROR_INJECTION()

block/blk-core.c uses ALLOW_ERROR_INJECTION(), which is defined in
asm-generic/error-injection.h. It currently relies on this header being
included indirectly through linux/module.h -> linux/error-injection.h.

Add the missing include in preparation for removing the
linux/error-injection.h include from linux/module.h.
