FDPIC: For-loop in elf_core_vma_data_size() is incorrect

Fix an incorrect for-loop in elf_core_vma_data_size().  The advance-pointer
statement lacks an assignment:

	  CC      fs/binfmt_elf_fdpic.o
	fs/binfmt_elf_fdpic.c: In function 'elf_core_vma_data_size':
	fs/binfmt_elf_fdpic.c:1593: warning: statement with no effect
