scsi: ufs: core: Rename ufshcd_wb_presrv_usrspc_keep_vcc_on()
The ufshcd_wb_presrv_usrspc_keep_vcc_on() function has deviated from its
original implementation. The "_keep_vcc_on" part of the function name is
misleading. Rename the function to ufshcd_wb_curr_buff_threshold_check()
to improve the readability. Also, updated the comments in the function.
There is no change to the functionality.
