[PATCH] ACPI: APEI: EINJ: Fix einj_tab memleak in einj_probe()

[Zhen Ni <zhen.ni@easystack.cn>]

Fixes a permanent ACPI table memory leak when einj_probe() return 0 by
adding acpi_put_table().
Remove the assignment rc = -ENOMEM to allow the function to propagate
the actual return value.

Fixes: e40213450b53 ("ACPI, APEI, EINJ support")
