[PATCH 1/2] nvme-tcp: initialize the mq_map to NULL

[Chaitanya Kulkarni <kch@nvidia.com>]

Initialize the local variable mq_map to NULL to remove the kernel
test robot warning.

drivers/nvme/host/tcp.c:1594:13: warning: variable 'mq_map' is used
uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]

Fixes: bd0f5c103101 ("nvme-tcp: Fix I/O queue cpu spreading for multiple controllers")  
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202501091328.r4kJ6xhy-lkp@intel.com/
