net: ti: icss-iep: Fix incorrect type for return value in extts_enable()

[ Upstream commit 5f1d1d14db7dabce9c815e7d7cd351f8d58b8585 ]

The variable ret in icss_iep_extts_enable() was incorrectly declared
as u32, while the function returns int and may return negative error
codes. This will cause sign extension issues and incorrect error
propagation. Update ret to be int to fix error handling.

This change corrects the declaration to avoid potential type mismatch.
