PATCH v2 1/1 arch/unicore32/kernel/ksyms.c: remove 2 export symbols to avoid compiling failure

'csum_partial' and 'csum_partial_copy_from_user' have already been exported in "lib/", so need not export them again, or it will cause compiling error.

The related error (with allmodconfig under unicore32):

LD vmlinux.o
lib/built-in.o:(___ksymtab+csum_partial+0x0): multiple definition of __ksymtab_csum_partial' arch/unicore32/kernel/built-in.o:(___ksymtab+csum_partial+0x0): first defined here lib/built-in.o:(___ksymtab+csum_partial_copy_from_user+0x0): multiple definition of __ksymtab_csum_partial_copy_from_user' arch/unicore32/kernel/built-in.o:(___ksymtab+csum_partial_copy_from_user+0x0): first defined here
make: *** [vmlinux] Error 1

Thanks, and this is a common error in most architectures.
