[PATCH] KEYS: fix compilation warnings in the dump_options() function

[Ye Bin]

From: Ye Bin <yebin10 at huawei.com>

There's issue as follows:
security/keys/trusted-keys/trusted_caam.c: In function ‘dump_options’:
security/keys/trusted-keys/trusted_caam.c:37:20: note: the ABI of passing struct with a flexible array member has changed in GCC 4.4
   37 | static inline void dump_options(struct caam_pkey_info pkey_info)
      |                    ^~~~~~~~~~~~

To solve the above problem, pass 'struct caam_pkey_info*' type parameter
to the dump_options() function.

Fixes: 9eb25ca6c973 ("KEYS: trusted: caam based protected key")
