Fix: SD_MMC deinit (espressif#5732)

* SD.open() new feature for creating all folders in path

This PR adds to the SD.open() function option to create all folders to the file.

SD.open(const char* path, const char* mode, const bool create)

Default value of create is false.
When true folders are created.

From issue espressif#5019

* Update vfs_api.cpp

memccpy -> memcpy

* SD_MMC deinit fix

Wrong deinit function was called.
