nvme/host: Fix RCU list traversal to use SRCU primitive
The code currently uses list_for_each_entry_rcu() while holding an SRCU
lock, triggering false positive warnings with CONFIG_PROVE_RCU=y
enabled:
drivers/nvme/host/core.c:3770 RCU-list traversed in non-reader section!!
While the list is properly protected by SRCU lock, the code uses the wrong
list traversal primitive. Replace list_for_each_entry_rcu() with
list_for_each_entry_srcu() to correctly indicate SRCU-based protection
and eliminate the false warning.
Fixes: be647e2c76b2 ("nvme: use srcu for iterating namespace list")
