dma-mapping: fix m32r build warning
kbuild test robot reports: In file included from include/linux/skbuff.h:34:0, from include/linux/icmpv6.h:4, from include/linux/ipv6.h:75, from include/net/ipv6.h:16, from include/linux/sunrpc/clnt.h:27, from include/linux/nfs_fs.h:30, from fs/lockd/clntlock.c:13: include/linux/dma-mapping.h: In function 'dma_map_resource': >> include/linux/dma-mapping.h:274:16: warning: unused variable 'pfn' [-Wunused-variable] unsigned long pfn = __phys_to_pfn(phys_addr); ^~~ The pfn value is only used once in the call to pfn_valid(), remove the variable and calculate the pfn when it's needed. Note that the kbuild report is old and PHYS_PFN() is now used instead of __phys_to_pfn() to calculate the pfn.
