[PATCH RESEND] mpt3sas:Fix missing error checks for calls to _transport_phy_reset in mpt3sas_transport.c

[Nicholas Krause]

This adds the missing error checks and paths for functions that
call _transport_phy_reset and do not correctly check that the
call to this particular function has succeeded by returning zero
in the file, mpt3sas_transport.c.
