lsm,fs: fix vfs_getxattr_alloc() return type and caller error paths
The vfs_getxattr_alloc() function currently returns a ssize_t value
despite the fact that it only uses int values internally for return
values. Fix this by converting vfs_getxattr_alloc() to return an
int type and adjust the callers as necessary. As part of these
caller modifications, some of the callers are fixed to properly free
the xattr value buffer on both success and failure to ensure that
memory is not leaked in the failure case.
