USB: usb-storage: ene_ub6250: restore media-ready check

Commit 1892bf90677a ("USB: usb-storage: Fix use of bitfields for
hardware data in ene_ub6250.c") converted the media status fields from
bitfields to bit masks.

The original ene_transport() test called ene_init() only when neither
media type was ready:

        !(sd_ready || ms_ready)

The converted test became:

        !sd_ready || ms_ready

This is not equivalent. Restore the original semantics by testing that
both ready bits are clear before calling ene_init().
