We get 10 warnings when building kernel with W=1:
drivers/scsi/megaraid/megaraid_sas_base.c:213:21: warning: no previous prototype for 'megasas_get_cmd' [-Wmissing-prototypes]

drivers/scsi/megaraid/megaraid_sas_base.c:3902:5: warning: no previous prototype for 'megasas_alloc_cmds' [-Wmissing-prototypes]

In fact, these functions are declared in
drivers/scsi/megaraid/megaraid_sas_fusion.c, but should be
declared in a header file. thus can be recognized in other file.

So this patch moves the declarations into
drivers/scsi/megaraid/megaraid_sas.h.
