[PATCH v3 04/12] landlock: Rename quiet_masks to quiet_access

[Mickaël Salaün]

The base stores the fs/net/scope quiet bitmasks in a struct access_masks
field named quiet_masks.  A following commit adds the sibling struct
perm_masks field quiet_perm for capabilities and namespaces.
quiet_masks drops the access category and keeps the type half
("masks"), while quiet_perm keeps the category and drops the type half,
so the two read as an inconsistent pair.

Rename the base field to quiet_access, giving the symmetric,
category-named pair quiet_access/quiet_perm that also matches the UAPI
handled_access_*/quiet_access_* naming.  This is a no-functional-change
rename.
