bnx2x: allow bnx2x_bsc_read() to schedule
bnx2x_warpcore_read_sfp_module_eeprom() can call bnx2x_bsc_read()
three times before giving up.
This causes latency blips of at least 31 ms (58 ms being reported
by our teams)
Convert the long lasting loops of udelay() to usleep_range() ones,
and breaks the loops on precise time tracking.
