nvmem: meson-efuse: Fix return value of nvmem callbacks
Read/write callbacks registered with nvmem core expect 0 to be returned
on success and a negative value to be returned on failure.
meson_efuse_read() and meson_efuse_write() call into
meson_sm_call_read() and meson_sm_call_write() respectively which return
the number of bytes read or written on success as per their api
description.
Fix to return error if meson_sm_call_read()/meson_sm_call_write()
returns an error else return 0.
