dax: fix FS_DAX=n BLOCK=y compilation
The 0day kbuild robot reports:
>> drivers//dax/super.c:64:20: error: redefinition of 'fs_dax_get_by_bdev'
struct dax_device *fs_dax_get_by_bdev(struct block_device *bdev)
^~~~~~~~~~~~~~~~~~
In file included from drivers//dax/super.c:22:0:
include/linux/dax.h:76:34: note: previous definition of 'fs_dax_get_by_bdev' was here
static inline struct dax_device *fs_dax_get_by_bdev(struct block_device *bdev)
^~~~~~~~~~~~~~~~~~
Protect the definition of fs_dax_get_by_bdev() in drivers/dax/super.c
with an ifdef.
Fixes: 78f354735081 ("dax: introduce a fs_dax_get_by_bdev() helper")
