[PATCH -next] evm: remove set but not used variable 'xattr'

[YueHaibing <yuehaibing@xxxxxxxxxx>]

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

security/integrity/evm/evm_main.c: In function 'init_evm':
security/integrity/evm/evm_main.c:566:21: warning:
 variable 'xattr' set but not used [-Wunused-but-set-variable]

It never used since commit 21af76631476 ("EVM: turn evm_config_xattrnames
into a list")
