scsi: ufs: send request sense after the link reinitialization
After link reintialization, device would set the UNIT ATTENTION condition
for each logical units. UNIT ATTENTION condition gets automatically
cleared on either receiving explicit REQUEST SENSE command or data commands
to LUs. Although some devices may stop responding to data commands if we do
UFS link hibern8 enter/exit after link reinitialization but before any data
commands. This change works around above mentioned issue by sending
the explicit REQUEST SENSE command to all LUs after the link
reinitialization.
