Subject: [PATCH v4] usb: cdns3: Rids of duplicate error message

On failure, the platform_get_irq_byname prints an error message,
so patch removes error message related to this function from
core.c file.

A change was suggested during reviewing CDNSP driver by Chunfeng Yun.

Changelog:
v4
- fixed typo.
- "Acked-by" tag has been added.
v3
- changed error condition checking for dev_irq.
v2
- simplified code as sugested by Roger Quadros.
