[PATCH] FMC: remove duplicated fru_strlen and unused variable len

[Colin King <colin.king@canonical.com>]

From: Colin Ian King <colin.king@canonical.com>

The call to fru_strlen on tl is performed twice; remove the duplicate
and the unsed variable len. This fixes the clang warning:

drivers/fmc/fru-parse.c:39:2: warning: Value stored to 'len' is never read
