Blackfin: Annotate strnlen_user and strlen_user 'src' parameter with __user
The 'src' parameter of strnlen_user and strlen_user is supposed to take a
userspace pointer, so annotate it with __user. This fixes the following and
similar sparse warnings:
fs/binfmt_elf_fdpic.c:671:36: warning: incorrect type in argument 1 (different address spaces)
fs/binfmt_elf_fdpic.c:671:36: expected char const *src
fs/binfmt_elf_fdpic.c:671:36: got char [noderef] <asn:1>*[assigned] p
fs/binfmt_elf_fdpic.c:683:36: warning: incorrect type in argument 1 (different address spaces)
fs/binfmt_elf_fdpic.c:683:36: expected char const *src
fs/binfmt_elf_fdpic.c:683:36: got char [noderef] <asn:1>*[assigned] p
