[PATCH] ARM: module: remove 'always false' statement

[Austin Kim]

The each field of 'struct elf32_rel' is declared as below.
typedef struct elf32_rel {
   Elf32_Addr r_offset;
   Elf32_Word r_info;
} Elf32_Rel;

typedef __u32 Elf32_Addr;
typedef __u32 Elf32_Word;

This means that 'r_offset' and 'r_info' could contain non-negative value.
So 'always false' statement can be dropped.
