[PATCH] KEYS: trusted: Remove set but not used variable 'keyhndl'

[zhengbin]

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

security/keys/trusted-keys/trusted_tpm1.c: In function tpm_unseal:
security/keys/trusted-keys/trusted_tpm1.c:588:11: warning: variable keyhndl set but not used [-Wunused-but-set-variable]

It is introduced by commit 00aa975bd031 ("KEYS: trusted:
Create trusted keys subsystem"), but never used, so remove it.
