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.
