[PATCH] fuse: cache POSIX ACLs when setting them

[Luis Henriques <luis@igalia.com>]

When setting an ACL in an inode we can immediately add it to the cache.
This is a small optimisation, as currently an ACL is only added to the
cache when reading it again, which involves an extra GETXATTR hop into
user-space.
