block: Turn bvec_k{un,}map_irq() into static inline functions
Convert bvec_k{un,}map_irq() from macros to static inline functions if
!CONFIG_HIGHMEM, so we can easier detect mistakes like the one fixed in
93055c31045a2d5599ec613a0c6cdcefc481a460 ("ps3disk: passing wrong variable =
to
bvec_kunmap_irq()")
