[PATCH] vfs: fix boolreturn.cocci warnings

[kbuild test robot]

fs/namespace.c:1185:9-10: WARNING: return of 0/1 in function 
'path_is_mountpoint' with return type bool
fs/namespace.c:1199:9-10: WARNING: return of 0/1 in function 
'path_is_mountpoint_rcu' with return type bool

 Return statements in functions returning bool should use
 true/false instead of 1/0.
