mtd: physmap_of_gemini: Fix disabled pinctrl state check

[ Upstream commit b7c0982 ]

The condition for checking the disabled pinctrl state incorrectly checks
gf->enabled_state instead of gf->disabled_state. This causes misleading
error messages and could lead to incorrect behavior when only one of the
pinctrl states is defined.

Fix the condition to properly check gf->disabled_state.
