cachefiles: Fix oops in vfs_mkdir from cachefiles_get_directory
Commit c54b386969a5 ("VFS: Change vfs_mkdir() to return the dentry.")
changed cachefiles_get_directory, replacing "subdir" with a ERR_PTR
from the result of cachefiles_inject_write_error, which is either 0
or some error code. This causes an oops when the resulting pointer
is passed to vfs_mkdir.
Use a similar pattern to what is used earlier in the function; replace
subdir with either the return value from vfs_mkdir, or the ERR_PTR
of the cachefiles_inject_write_error() return value, but only if it
is non zero.
Fixes: c54b386969a5 ("VFS: Change vfs_mkdir() to return the dentry.")
