drivers: nfc: nfcsim: remove return value check of `dev_dir`
Smatch complains that:
nfcsim_debugfs_init_dev() warn: 'dev_dir' is an error pointer or valid
According to the documentation of the debugfs_create_dir() function,
there is no need to check the return value of this function.
Just delete the dead code.
