bnx2fc: reduce stack usage in __bnx2fc_enable
When the bnx2fc driver was changed to read the npiv table from nvram, the stack of the __bnx2fc_enable function gained an additional 1028 byte structure that gcc rightfully warns about: drivers/scsi/bnx2fc/bnx2fc_fcoe.c: In function '__bnx2fc_enable': drivers/scsi/bnx2fc/bnx2fc_fcoe.c:2134:1: warning: the frame size of 1128 bytes is larger than 1024 bytes [-Wframe-larger-than=] In order to avoid a possible kernel stack overflow and to get rid of the warning, this changes the function to use a dynamic allocation of the structure using kzalloc.
