mailbox: qcom-ipcc: fix incorrect num_chans counting 

[ Upstream commit a493208079 ]

Breaking out early when a match is found leads to an incorrect num_chans
value when more than one ipcc mailbox channel is used by the same device.

Fixes: e9d50e4b4d ("mailbox: qcom-ipcc: Dynamic alloc for channel arrangement")
