Linux 6.6: Pass request_mask to generic_fillattr

Browse Source 
The Linux 6.6 commit: "fs: pass the request_mask to generic_fillattr"
(0d72b92883) added an additional parameter to Linux's
generic_fillattr() function.

For openafs, generic_fillattr() is called from the inode_operations
method "getattr", which is implemented in afs_linux_getattr(). The value
for the request_mask parameter is an existing parameter that is passed
to the inode_operations "getattr" method.

Add an autoconf test for 4 parameters to the generic_fillattr function
and update afs_linux_getattr() to pass the request_mask to
generic_fillattr().
