firmware: tegra: Fix error return code in tegra210_bpmp_init()

Browse Source 
[ Upstream commit 7fea67710e9f6a111a2c9440576f2396ccd92d57 ]

When call irq_get_irq_data() to get the IRQ's irq_data failed, an
appropriate error code -ENOENT should be returned. However, we directly
return 'err', which records the IRQ number instead of the error code.
