fs/fatfs: Fix open for write
When fatfs_open() was called to open file
for writing it set FA_WRITE flag to fat driver.
It is enough if file already exists but if
it first call to open file to write it always
failed.
Now additional flag FA_OPEN_ALWAYS is added
to make sure file will be created if it's not
present yet.
For FS_ACCESS_READ only flag file still must
exists before.
