Re: [PATCH] drivers: net: xgene: initialize slots

From: Colin Ian King <redacted>

static analysis using cppcheck detected that slots was uninitialized.
Fix this by initializing it to buf_pool->slots - 1

Found using static analysis with CoverityScan, CID #1387620

Fixes: a9380b0f7be818 ("drivers: net: xgene: Add support for Jumbo frame")
