[PATCH -next] KEYS: trusted: remove set but not used variable ''

[YueHaibing]

Fixes gcc '-Wunused-but-set-variable' warning:

security/keys/trusted.c: In function 'tpm_unseal':
security/keys/trusted.c:592:11: warning:
 variable 'keyhndl' set but not used [-Wunused-but-set-variable]
  uint32_t keyhndl;

It never used since introduction in 
commit d00a1c72f7f4 ("keys: add new trusted key-type")
