Workaround recursive error

Workaround recursive error

It looks like there is a bug in our configuration system when we add the
additional dependencies in PKG_DEFAULT_DEPENDS we get these recursive
errors:
----------------------------
tmp/.config-package.in:19514:error: recursive dependency detected!
tmp/.config-package.in:19514:	symbol PACKAGE_kmod-cfg80211 depends on PACKAGE_kmod-cfg80211
For a resolution refer to Documentation/kbuild/kconfig-language.rst
subsection "Kconfig recursive dependency limitations"

tmp/.config-package.in:19115:error: recursive dependency detected!
tmp/.config-package.in:19115:	symbol PACKAGE_kmod-b43 depends on PACKAGE_kmod-b43
For a resolution refer to Documentation/kbuild/kconfig-language.rst
subsection "Kconfig recursive dependency limitations"

tmp/.config-package.in:18681:error: recursive dependency det
----------------------------

Just remove the dependency on iw.
