ext2: mark s_mount_state as guarded by s_lock

s_mount_state tracks the filesystem's mount/error state and is protected
by s_lock everywhere it is accessed. Annotate it with __guarded_by() for
Clang's context analysis.

ext2_setup_super() reads s_mount_state and is called with s_lock held
from the remount path, so annotate it with __must_hold().

There are two accesses (the initial read in ext2_fill_super() and the
setup_super() call) in the mount flow. This is before the superblock
is live, so no concurrent access should be possible. Convert the
spinlock initialization to use guard(spinlock_init) to prevent
warnings on the writes later in initialization.
