interconnect: qcom: icc-rpm: Set the count member before accessing the flex array
The following UBSAN error is reported during boot on the db410c board on
a clang-19 build:
Internal error: UBSAN: array index out of bounds: 00000000f2005512 [#1] PREEMPT SMP
...
pc : qnoc_probe+0x5f8/0x5fc
...
The cause of the error is that the counter member was not set before
accessing the annotated flexible array member, but after that. Fix this
by initializing it earlier.
