nvmem: core: Check read_only flag for force_ro in bin_attr_nvmem_write()
commit da9596955c05966768364ab1cad2f43fcddc6f06 upstream.
The bin_attr_nvmem_write() must check the read_only flag and block
writes on read-only devices, now that a nvmem device can be switched
between read-write and read-only mode at runtime using the force_ro
attribute. Add the missing check.
Fixes: 9d7eb234ac7a ("nvmem: core: Implement force_ro sysfs attribute")
