fs: fix ext4 write() conditional assignment
The Kconfig for the ext4 filesystem has a dedicated option to enable
write support documented in doc/README.ext4:
> First, to enable support for both ext4 (and, automatically, ext2 as well),
> but without selecting the corresponding commands, enable one of the following:
> CONFIG_FS_EXT4 (for read-only)
> CONFIG_EXT4_WRITE (for read-write)
Currently, ext4 write is only enabled if we select CONFIG_*CMD*_EXT4,
which is wrong.
