[PATCH v2] edac: remove redundant error print in xgene_edac_probe

[menglong8 . dong]

From: Menglong Dong <dong.menglong@xxxxxxxxxx>

Coccinelle reports a redundant error print in xgene_edac_probe.
As 'platform_get_irq' already prints the error message, error
print here is redundant.

Fix it by using 'platform_get_irq_optional' in place of
'platform_get_irq', as Robert suggested.

v2:
- use 'platform_get_irq_optional' instead of 'platform_get_irq'
