sfc: Fix loop condition for efx_filter_search() when !for_insert
efx_filter_remove_filter() fails to remove inserted filters in some cases.
For example:
1. Two filters A and B have specifications that result in an initial
hash collision.
2. A is inserted first, followed by B.
3. An attempt to remove B first succeeds, but if A is removed first
a subsequent attempt to remove B fails.
When searching for an existing filter (!for_insert),
efx_filter_search() must always continue to the maximum search depth
for the given type rather than stopping at the first unused entry.
