[PATCH] IDE: always release DMA engine

[Sergei Shtylylov <sshtylyov@xxxxxxxxxxxxx>]

Hail.

    Release the DMA engine for the custom mapping IDE drivers also (for
example, siimage.c does allocate it in both I/O-mapped and custom-mapped
modes). Remove useless code from the error path of ide_allocate_dma_engine().

WBR, Sergei
