scsi: ufs: core: bsg: Fix sometimes-uninitialized warnings 

Compilation complains that two possible variables are used without
initialization:

drivers/ufs/core/ufs_bsg.c:112:6: warning: variable 'sg_cnt' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]
drivers/ufs/core/ufs_bsg.c:112:6: warning: variable 'sg_list' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]

Fix both warnings by adding initialization with sg_cnt = 0, sg_list = NULL.

Fixes: 6ff265fc5e ("scsi: ufs: core: bsg: Add advanced RPMB support in ufs_bsg")
