[PATCH -next v2] i3c: master: svc: drop free_irq of devm_request_irq allocated irq

[Yang Yingliang]

irq allocated with devm_request_irq() will be freed in devm_irq_release(),
using free_irq() in ->remove() will causes a dangling pointer, and a
subsequent double free. So remove the free_irq() in svc_i3c_master_remove().
