[PATCH][V2][next] fs/9p: replace functions v9fs_cache_{register|unregister} with direct calls

[Colin Ian King]

The helper functions v9fs_cache_register and v9fs_cache_unregister are
trivial helper functions that don't offer any extra functionality and
are unncessary. Replace them with direct calls to v9fs_init_inode_cache
and v9fs_destroy_inode_cache respectively to simplify the code.

V1: originally cleaned up v9fs_cache_register to just a direct call
    to v9fs_init_inode_cache.
V2: replace v9fs_cache_register and v9fs_cache_unregister with direct
    calls and change subject line
